چکیده
Cyclohexanone and cycloheptanone can be enantioselectively functionalized in the 3-position with up to 92% ee and 87% ee, respectively, by the base-promoted dimerization of the corresponding enones using 3,4,5-tribenzyloxybenzyl cinchoninium bromide, as a new effective catalyst.

Organocatalytic transfer hydrogenation of cyclic enones.
The first enantioselective organocatalytic transfer hydrogenation of cyclic enones has been accomplished. The use of iminium catalysis has provided a new organocatalytic strategy for the enantioselective reduction of beta,beta-substituted alpha,beta-unsaturated cycloalkenones, to generate beta-stereogenic cyclic ketones. The use of imidazolidinone 4 as the asymmetric catalyst has been found to ...
متن کاملBiomimetic and organocatalytic approaches to oxidation catalysis*
The lecture summarized our recent work in the fields of (i) catalytic asymmetric epoxidation and cyclopropanation, (ii) C–C coupling reactions, and (iii) dynamic kinetic resolution (DKR). The first section describes the use of chiral Ru-porphyrins as catalysts for the asymmetric epoxidation and cyclopropanation of nonfunctionalized olefins, and of peptides and alkaloid-based phase-transfer cata...
متن کاملEnantioselective Stetter reactions of enals and modified chalcones catalyzed by N-heterocyclic carbenes.
Organocatalytic activation of readily available substrates has led to the rapid development of many enantioselective reactions in the last decade. In N-heterocyclic carbene (NHC) catalysis, reactions of enals with enones or enone derivatives have been extensively investigated and are reported to undergo a diverse set of transformations based on the catalytically generated enolate and homoenolat...
