Selective Synthesis of Substituted Pyrrole-2-phosphine Oxides and -phosphonates from 2H-Azirines and Enolates from Acetyl Acetates and Malonates

A simple and efficient selective synthesis of 1H-pyrrole-2-phosphine oxides 3 and -phosphonates 7 by addition of enolates derived from acetyl acetates to 2H-azirinylphosphine oxide 1 and -phosphonate 6 is reported. Nucleophilic addition of enolates derived from diethyl malonate to 2H-azirines 1 and 6 led to the formation of functionalized 2-hydroxy-1H-pyrrole-5-phosphine oxide 9 and -phosphonate 10, while vinylogous alpha-aminoalkylphosphine oxides 14 and -phosphonate 15 may be obtained from azirines and the enolate derived from diethyl 2-phenylmalonate. Ring closure of vinylogous derivatives 14 and 15 in the presence of base led to the formation of 1,5-dihydro-3-pyrrolin-2-ones containing a phosphine oxide 17 or a phosphonate group 18.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. 1977-07-7, you can contact me at any time and look forward to more communication. Category: pyrrolines.

Chemistry of Hermidin: Insights from Extraction Experiments with the Main Alkaloid of Mercurialis perennis L. Tracked by GC/MS and LC/MSn

Hermidin (1), a piperidine-2,3-dione alkaloid, has been previously detected as a lipophilic constituent in Mercurialis perennis L. and other Mercurialis species. Because of strong electron-withdrawing effects of its carbonyl groups, an acidic H-atom is easily subtracted from 1, whereas the latter shows high reactivity towards oxidation reactions or the attack of C-nucleophilic agents. To obtain a better understanding of possible chemical pathways upon extraction of root parts of M. perennis, the products obtained with different solvents from 1 were investigated. Extraction of M. perennis with aqueous MeOH or EtOH yielded a mixture of hermidin quinone (3), 5-hydroxy-4-methoxy-5-(alkoxycarbonyl)-1-methyl-3-pyrrolin-2-ones, 7 and 8, and d, l- and meso-isochrysohermidins, 5 and 6, all of them being investigated by GC/MS and LC/MSn. The latter compounds were supposedly formed by free-radical reactions, followed by spontaneous benzilic acid rearrangement and esterification. Furthermore, extraction of M. perennis with aqueous Me2CO produced an aldol condensation product, the known alkaloid speranskatine A (9a), which was identified by NMR after chromatographic purification. In a similar manner, a CH2 homolog of speranskatine A (10a) was obtained as a novel compound when ethyl methyl ketone (= butan-2-one; EtCOMe) instead of Me2CO was used for extraction. Consequently, 1 easily undergoes artefact formation upon extraction of plant material with polar or slightly polar solvents.

Straightforward coordination-driven supramolecular chemistry preparation of a discrete solid-state luminescent Cu-4 polymetallic compact assembly based on conformationally flexible building blocks

The ditopic nitrile-capped 1,4-phenylenediacetonitrile linker L-3 featuring partial conformational flexibility was reacted with a flexible pre-assembled Cu(I) dimer stabilized by the bis(diphenyl-phosphino)methane dppm ligand along adaptive coordination-driven supramolecular assembling processes. It resulted in the selective and unexpected formation of a compact tetrametallic assembly associating two bimetallic building blocks with three ditopic linkers. The solid-state photophysical studies of this original Cu(I)-based assembly were analysed and showed its attractive luminescence properties.

Synthesis of Spiro-Delta(2)-Pyrrolin-4-One Pseudo Enantiomers via an Organocatalyzed Sulfa-Michael/Aldol Domino Sequence

Delta(2)-Pyrrolin-4-ones undergo organocatalyzed sulfa-Michael/aldol domino spirocyclizations with mercaptoacetaldehyde dimer. The products contain three contiguous stereocenters (ee up to 99%, dr up to 95:5, 25 examples) and can be transformed into analogues of natural products. With the use of a single catalyst, the absolute configuration of the products were determined by the configuration of the exocyclic double bond of the starting material. These results point at the possibility of a widespread use of unsaturated Delta(2)-pyrrolin-4-ones in various (organo)catalyzed (cascade) transformations for accessing libraries of 3D-rich pyrrolone-based (spiro)heterocycles.

Vacuum-Ultraviolet Absorption Spectrum of 3-Methoxyacrylonitrile

The high-resolution absorption spectrum of 3-methoxyacrylonitrile (3MAN) was measured between 5.27 and 12.59 eV using a synchrotron-based Fourier-transform spectrometer. It was related to an absolute absorption cross-section scale. Complementary calculations at the DFT-MRCl/aug-cc-pVTZ level of theory document the vertical transition energies and oscillator strengths toward the first 19 states of both the E and Z geometrical isomers of 3MAN. Comparisons with the experimental absorption spectrum reveal the similarities and differences between 3MAN, a bifunctional molecule, with acrylonitrile and methyl-vinylether, where only one functional group is present. As in acrylonitrile, several broad valence transitions were observed up to the ionization limit. They are likely associated with the extended pi-system induced by the nitrile group but might also involve sigma sigma* transitions close to the ionization limit. As in methylvinylether, Rydberg series converging to the ionization limit are absent. This is attributed to a difference in neutral and cationic geometry due to a 60 degrees rotation of the methyl group.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. 1977-07-7, you can contact me at any time and look forward to more communication. COA of Formula: https://www.ambeed.com/products/1977-07-7.html.

Dicumyl Peroxide used as curing Agent for different Types of Rubber Matrices Part I: Effect of Temperature

Several elastomers were cured with dicumyl peroxide at different vulcanization temperatures. The focus of the work was the investigation of the influence of curing temperature on curing characteristics of rubber compounds. Subsequently, crosslink density and physical mechanical properties of vulcanizates were evaluated. The results demonstrated that higher curing temperatures lead to a total acceleration of cross-linking process. The effect of temperature on the crosslink density was low and was dependent on the structure of tested rubbers. Physicalmechanical properties of vulcanizates were almost not influenced by curing temperature.

Racemic synthesis of the new antibiotic tetramic acid reutericyclin

The synthesis of the new bacteriocidal compound reutericyclin, 3-acetyl-1-(2-trans-decenoyl)-2-hydroxy-5-isobutyl-Delta(2)-pyrrolin-4-one, is performed by coupling of N-(2-trans-decenoyl)-L-leucine to Meldrum’s acid followed by cyclization. The resulting N-acylated tetramic acid is directly C-acetylated in position 3. HPLC-purification on RP-C-18 gave racemic reutericyclin in high purity. 2D-NMR and FT-ICR-MS data are identical with those of natural reutericyclin.

Targeted development of hydrophilic porous polysulfonamide gels with catalytic activity

We report the use of a template and functional monomers in the synthesis of three novel polysulfonamide gels with new architectures and functional groups. These mesoporous polysulfonamide gels were prepared by the condensation polymerization of benzene-1,3-disulfonyl chloride (as the main precursor), linear monomers, and cross-linkers (as variable precursors) in the presence of a silica template by a combination of sol-gel chemistry and the nanocasting technique. In this synthesis pathway, in situ polymerization onto the template surface led to the construction of a silica/polymer nanocomposite. Next, after removal of the template, the nanocomposite gels were transformed into mesoporous polysulfonamide nanospheres. After the physicochemical identification of the synthesized materials, functionalized polysulfonamides were used as reusable novel catalysts with high efficiency for the Strecker reaction under mild conditions. These polymers have Brunsted/Lewis acid active sites, a mesoporous structure, and hydrogen bonding. Moreover, since these polymers are hydmgels that can absorb water, they can promote the Strecker reaction through chemical absorption of the generated water as a driving force. Overall, this article describes a novel synthesis procedure and application of porous polysulfonamide gels.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 1977-07-7. The above is the message from the blog manager. Computed Properties of https://www.ambeed.com/products/1977-07-7.html.
