Chiral diols with three contiguous stereocenters were synthesized by a highly enantioselective ruthenium-catalyzed asymmetric hydrogenation of racemic α,α′-disubstituted cycloketones involving dynamic kinetic resolution. This new catalytic asymmetric method provides a concise route to the alkaloid (+)-γ-lycorane. Copyright

In this paper, we present an asymmetric alkylation of modified 2-arylcyclohexanones that employs a novel chiral ammonium bromide as a phase-transfer catalyst and an achiral auxiliary as a controller to improve the enantioselectivity to afford optically enriched products having a chiral quaternary carbon center.
ELECTROCHEMICAL FORMATION OF INDAZOLES FROM TROPONE TOSYLHYDRAZONES: ELECTROCHEMICAL OXIDATIONS OF SODIUM SALTS OF TOSYLHYDRAZONES OF TROPONE AND 2-PHENYLTROPONE

Electrochemical oxidations of the sodium salts of tropone and 2-phenyltropone tosylhydrazones afforded 2-tosyl-2H-indazole and 1-tosyl-7-phenyl-1H-indazole, respectively.The reactions proceeded through the cyclizations of the corresponding hydrazyl radica
