Abstract

Abstract α-Alkyl-β-hydroxy esters were obtained via dynamic kinetic resolution (DKR) employing purified or crude E. coli overexpressed alcohol dehydrogenases (ADHs). ADH-A from R. ruber, CPADH from C. parapsilosis and TesADH from T. ethanolicus afforded syn- (2R, 3S) derivatives with very high selectivities for sterically not impeded ketones ('small- bulky'substrates), while ADHs from S. yanoikuyae (SyADH) and Ralstonia sp.(RasADH) ...
