Synthesis of stereocontrolled α,α-difluoro-β-hydroxycarbonyl materials
摘要:
Synthesis and synthetic utilities of stereocontrolled alpha, alpha-di fluoro-beta-hydroxy-gamma,delta-unsaturated carbonyl compounds via enzymatic resolution with lipase PS (Pseudomonas cepacia, Amano Pharmaceutical Co. Ltd.) or lipase MY (Candida rugosa, Meito Sangyo Co. Ltd.) were described, and then the absolute configuration of obtained chiral materials was determined by the modified Mosher's method.
