Stereoinversion ofR-Configured Secondary Alcohols Using a Single Enzymatic Approach

Demonstration of Redox Potential of Metschnikowia koreensis for Stereoinversion of Secondary Alcohols/1,2-Diols

The present work reports the Metschnikowia koreensis-catalyzed one-pot deracemization of secondary alcohols/1,2-diols and their derivatives with in vivo cofactor regeneration. Reaction is stereoselective and proceeds with sequential oxidation of (R)-secondary alcohols to the corresponding ketones and the reduction of the ketones to (S)-secondary alcohols. Method is applicable to a repertoire of...

Ruthenium-Catalyzed Amination of Secondary Alcohols using Borrowing Hydrogen Methodology.

A new ruthenium complex catalyzes the amination of primary and secondary alcohols and the regioselective mono- and sequential diamination of diols via the borrowing hydrogen pathway. Several variations on new intra- and intermolecular cyclizations of aminoalcohols, diols and diamines lead to heterocyclic ring systems.

Ni-catalysed, domino synthesis of tertiary alcohols from secondary alcohols.

The use of in situ generated (NHC)-Ni catalytic species (NHC = N-heterocyclic carbene) allows for the synthesis, in short reaction times, of a variety of tertiary alcohols from secondary alcohols through a domino oxidation-addition protocol.

Producing specific secondary alcohols via ketone catalysis

Jing Wu et al. have synthesized enantiomerically pure secondary alcohols under mild reaction conditions. The stereospecific alcohols, formed by the hydrosilylation of prochiral ketones, are intermediates in the manufacturing of industrial compounds and pharmaceuticals. Previous methods for creating the alcohols have been hampered by the high cost of metal catalysts, low substrate-to-catalyst ra...
