Lipase-promoted kinetic resolution of racemic, P-chiral hydroxymethylphosphonates and phosphinates
摘要:
Lipase-mediated acetylation of racemic P-chiral hydroxymethylphosphonates and phosphinates, and hydrolysis of their O-acetyl derivatives have been conducted under kinetic resolution conditions to give the enantiomerically enriched title products with up to 92% ee. Their absolute configuration has been determined by means of chemical correlation and CD measurements. (C) 1998 Elsevier Science Ltd. All rights reserved.
