Probing the Peroxycarbenium [3+2] Cycloaddition Reactions with 1,2-Disubstituted Ethylenes: Results and Insights

The causes for the title reaction to be limited to only the alkenes with an unsubstituted terminal alkenic carbon were explored. In some ?failed? cases the cycloaddition products actually formed but rearranged concurrently. An oxygen atom or a N-Boc (Boc=tert-butyloxycarbonyl) group at the double bond was proven essential for acquisition of intact [3+2] cycloaddition products from 1,2-disubstituted ethylenes.

Rhodium-catalysed syn-carboamination of alkenes via a transient directing group

Alkenes are the most ubiquitous prochiral functional groups – those that can be converted from achiral to chiral in a single step – that are accessible to synthetic chemists. For this reason, difunctionalization reactions of alkenes (whereby two functional groups are added to the same double bond) are particularly important, as they can be used to produce highly complex molecular architectures. Stereoselective oxidation reactions, including dihydroxylation, aminohydroxylation and halogenation, are well established methods for functionalizing alkenes. However, the intermolecular incorporation of both carbon- and nitrogen-based functionalities stereoselectively across an alkene has not been reported. Here we describe the rhodium-catalysed carboamination of alkenes at the same (syn) face of a double bond, initiated by a carbon-hydrogen activation event that uses enoxyphthalimides as the source of both the carbon and the nitrogen functionalities. The reaction methodology allows for the intermolecular, stereospecific formation of one carbon-carbon and one carbon-nitrogen bond across an alkene, which is, to our knowledge, unprecedented. The reaction design involves the in situ generation of a bidentate directing group and the use of a new cyclopentadienyl ligand to control the reactivity of rhodium. The results provide a new way of synthesizing functionalized alkenes, and should lead to the convergent and stereoselective assembly of amine-containing acyclic molecules.

Br¡ãnsted acid catalyzed proto-functionalization of enecarbamates and enamides: A convenient route to N,O-acetals

N,O-acetals are important structures found in many bioactive natural products, and this unique organic functional group can serve as a useful synthetic precursor to the unstable N-acylimines. In this paper, a convenient route to synthesize N-carbamoyl-N,O-acetals and N-acyl-N,O-acetals from enecarbamates and enamides in the presence of alcohols as the solvents and nucleophile sources under Br¡ãnsted acid conditions was reported. This strategy could be used to prepare various N,O-acetals from a range of enecarbamates and enamides with light alcohols, and the products are obtained in good yields (52?98%).

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 73286-71-2, and how the biochemistry of the body works.Related Products of 73286-71-2

RhII-Catalyzed beta-C(sp2)?H Alkylation of Enol Ethers, Enamides and Enecarbamates with alpha-Diazo Dicarbonyl Compounds

A RhII-catalyzed method for intermolecular alkylation of the beta-C(sp2)?H bond of enol ethers, enamides, and enecarbamates with alpha-diazo-1,3-dicarbonyl compounds is reported. The products are formed in up to 99 % yield and can be readily derivatized under a variety of conditions. By utilizing a combination of experimental and computational studies, the presumptive addition?elimination reaction mechanism was investigated and found to proceed under thermodynamic control at higher temperature. The acquired fundamental knowledge was translated into a strategic reaction design and yielded the first example of the beta-C?H functionalizations of acyclic enol ethers using alpha-diazo-1,3-dicarbonyl compounds.

Backbone-Modified Bisdiazaphospholanes for Regioselective Rhodium-Catalyzed Hydroformylation of Alkenes

A series of tetraaryl bisdiazaphospholane (BDP) ligands were prepared varying the phosphine bridge, backbone, and substituents in the 2- and 5-positions of the diazaphospholane ring. The parent acylhydrazine backbone was transformed to an alkylhydrazine via a borane reduction procedure. These reduced ligands contained an all sp3 hybridized ring mimicking the all sp3 phospholane of (R,R)-Ph-BPE, a highly selective ligand in asymmetric hydroformylation. The reduced bisdiazaphospholane (red-BDP) ligands were shown crystallographically to have an increased C-N-N-C torsion angle – this puckering resembles the structure of (R,R)-Ph-BPE and has a dramatic influence on regioselectivity in rhodium catalyzed hydroformylation. The red-BDPs demonstrated up to a 5-fold increase in selectivity for the branched aldehyde compared to the acylhydrazine parent ligands. This work demonstrates a facile procedure for increased branched selectivity from the highly active and accessible class of BDP ligands in hydroformylation.

Synthesis of indoles via 6pi-electrocyclic ring closures of trienecarbamates

A new method for the preparation of indoles from readily available alpha-haloenones and alpha-(trialkylstannyl)enecarbamates is described. Following a Stille coupling, trienecarbamate 2 is electronically activated to undergo a facile 6pi-electrocyclic ring closure and subsequent oxidation to afford protected aniline 4. Upon deprotection and reductive amination, acid 5 underwent clean cyclization to N-acetylindole 6 (Ac2O, NEt3, 130 C). This method has been used to construct a variety of substituted indoles that are not easily prepared by conventional indole annelation methods. Copyright
