One-Pot Synthesis of B-Aryl Carboranes with Sensitive Functional Groups Using Sequential Cobalt- and Palladium-Catalyzed Reactions

The simple and efficient method was developed for the one-pot synthesis of B-substituted aryl derivatives of ortho-carborane with functional groups sensitive to organolithium and organomagnesium reagents using 9-iodo-ortho-carborane and generated in situ organozinc compounds. The method proposed was used to prepare a series of 9-aryl-ortho-carboranes, including those containing nitrile and ester groups, 9-RC6H4-1,2-C2B10H11 (R = p-Me, p-NMe2, p-OCH2OMe, o-OMe, p-OMe, o-CN, p-CN, o-COOEt, m-COOEt, and p-COOEt). It was demonstrated that the same approach can be used for synthesis of diaryl derivatives of ortho-carborane 9,12-(RC6H4)(2)-1,2-C2B10H10 (R = H, p-Me). The solid-state structures of 9-RC6H4-1,2-C2B10H11 (R = p-NMe2, p-OCH2OMe, o-OMe, o-CN, p-CN, m-COOEt, and p-COOEt) and 9,12-(p-MeC6H4)(2)-1,2-C2B10H10 were determined by single crystal X-ray diffraction.

A pyrroline glucoside ester and steroidal saponins from Lilium martagon

A new phenylpropanoid ester of a pyrroline derivative and two new steroidal saponins were isolated from the fresh bulbs of Lilium martagon, along with several previously known compounds. The structures of the new compounds were determined by spectroscopic data, hydrolysis, and by comparison with spectral data of known compounds to be (-)-5-hydroxy-3-methyl-3-pyrrolin-2-one 5-O-(6-O-p-coumaroyl-beta-D-glucopyranoside), (25S)-spirost-5-ene-3 beta,17 alpha, 27-triol 3-O-(O-beta-D-glucopyranosyl-(1 –> 2)-O-beta-D-glucopyranosyl-(1 –> 4)-beta-D-glucopyranoside) and (25S)-5 alpha-spirostane-3 beta,17 alpha,27-triol 3-O-{O-beta-D-glucopyranosyl-(1 –> 2)-O-beta-D-glucopyranosyl-(1 –> 4)-beta-D-glucopyranoside}, respectively, Lilium martagon crosses well with L. hansonii to produce a valuable garden hybrid lily. In this study, the secondary metabolites of L. martagon were revealed to be closely related to those of L. hansonii, giving a good example of the correlation between the secondary metabolites and cross-compatibility.

Hydroxyapatite as a Potential Nanofiller in Technologically Useful Chlorinated Acrylonitrile Butadiene Rubber

This paper investigates the effect of hydroxyapatite nanoparticles (HA) on the cure characteristics, tensile and tear strength, elongation at break, hardness, abrasion resistance, heat build-up, resilience, glass transition temperature, oil resistance, alternating current (AC) conductivity and transport properties of chlorinated nitrile rubber (Cl-NBR). The maximum and minimum torque values were increased whereas the cure time values were decreased with the HA content in the Cl-NBR. The uniform dispersion of HA in Cl-NBR was obtained from scanning electron microscopy (SEM) and X-ray diffraction (XRD). Differential scanning calorimetry (DSC) showed the increased glass transition temperature of Cl-NBR with the addition of HA particles. Mechanical properties, conductivity and oil resistance of the composites were greatly increased with the loading of hydroxyapatite. Diffusion results were explained in terms of the loading of nanoparticles and size of the penetrant molecules. Arrhenius and thermodynamic parameters for the diffusion process have been estimated and an anomalous diffusion mechanism was observed.

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.

Organocatalyzed Asymmetric Mannich Reaction: An Update

The Mannich reaction is a multicomponent reaction resulting in aminoalkylation of an acidic proton placed next to a carbonyl functional group. It involves an appropriate carbonyl compound, such as formaldehyde and a primary or secondary amine or ammonia. The final product is a beta-amino-carbonyl compound known as a Mannich base. Reactions between aldimines and alpha-methylene carbonyls are also considered as Mannich reaction since these imines are generated from the reaction of amines and aldehydes. It comprises the reaction of primary or secondary amines or ammonia, formaldehyde and appropriate alpha-CH-acidic compounds (nucleophiles) such as carbonyl compounds having alpha-CH-acidic, nitriles, acetylenes, aliphatic nitro compounds, alpha-alkyl-pyridines or imines. Owing to the development of asymmetric organocatalysis, reports on asymmetric Mannich reaction have been drastically increased. The asymmetric Mannich reaction offers access to enantioenriched beta-amino ketones or beta-amino aldehydes, which are present as a scaffold in several natural products. Organocatalysts have been developed not only as a supplement to metal-catalyzed reactions or to biocatalysis, but nowadays, they are extensively used for the synthesis of various optically pure compounds that could not be achieved via metal- or biocatalyzed reactions. In this review, we try to update the advances in organocatalyzed asymmetric Mannich reactions, covering the recent advances of the subject from 2008 to date.

Conjugate addition reactions of alpha-aminoalkylcuprates with alpha,beta-alkenyl-, alpha,beta-alkynyl-, alpha,beta-beta,gamma-allenyl-, and alpha,beta-gamma,delta-dienyl carboxylie acid derivatives, nitriles, and sulfoxides

alpha -Aminoalkylcuprates prepared from alpha -lithio carbamates and CuCN.2LiCl participate in 1,4-addition reactions with alpha,beta -unsaturated esters, thiol esters, imides, and nitriles in poor to excellent yields depending upon the electron-withdrawing substituent and the substitution pattern of the unsaturated substrate. These reagents also undergo conjugate addition reactions with alpha,beta -alkynyl esters, sulfoxides, and nitriles and with alpha,beta-beta,gamma -unsaturated allenyl esters. Excellent stereocontrol is achieved in the conjugate additions of alpha -aminoalkylcuprates to the allenyl esters, while poor stereoselectivity results in the conjugate additions to the alkynyl derivatives. Deprotection and cyclization of the alkynyl adducts affords pyrrolin-2-ones, while similar treatment of the allenyl adducts affords 4-alkylidine- pyrrolidin-2-ones and pyrrolizidinones.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. 293298-33-6, you can contact me at any time and look forward to more communication.

Methylene Blue as a Photosensitizer and Redox Agent: Synthesis of 5-Hydroxy-1H-pyrrol-2(5H)-ones from Furans

A highly efficient and general singlet-oxygen-initiated one-pot transformation of readily accessible furans into 5-hydroxy-1H-pyrrol-2(5H)-ones has been developed. The methodology was extended to the synthesis of other high-value ,-unsaturated -lactams. This useful set of transformations relies not only on the photosensitizing ability of methylene blue, but also on its redox properties: properties that have until now been virtually ignored in a synthetic context.
