Enantioselective α-Hydroxylation of β-Keto Esters Catalyzed by Cinchona Alkaloid Derivatives
A highly efficient α-hydroxylation of β-ketoesters catalyzed by cupreidine in the presence of cumyl hydroperoxide (CHP) was achieved. The reaction was applied to a wide variety of β-ketoesters to give products in high yields (up to 95%) with excellent enantioselectivities (up to 97% ee). The reaction had been successfully scaled up to a gram quantity and (S)-5-chloro-2-hydroxy-1-oxo-2,3-dihydro-

triphenylsilanethiol as catalysts (5–10 mol% based on alkene). In the presence of the thiol, the slow direct abstraction of hydrogen from the silane by the nucleophilic adduct radical R1R2ĊCH2R3 is replaced by a cycle of more rapid polarity-matched reactions in which hydrogen-atomtransfer to the adduct radicalfrom the thiol is followed by abstraction of hydrogen from the silane by the derived thiyl radical, to regenerate

A highly efficient method for the oxidative coupling of 2‐substituted3‐oxindoles with aromatic compounds to form 2,2‐disubstituted indolin‐3‐ones with broad scope is described. This work utilized oxygen as the terminal oxidant and a base‐metal catalyst under mild conditions instead of toxic/precious‐metal reagents and higher‐molecular‐weight oxidants. Quaternary structures were produced in modest‐to‐excellent
