    摘要: An in vitro process for preparing 6((1R)-hydroxyethyl) penem acids by hydrolyzing the carboxylic ester derivative thereof using an enzyme capable of selectively hydrolyzing the ester group at the 3-position of the carboxylic acid ester using an esterase, acylase or lipase enzyme, wherein the enzymatic hydrolysis is effected at a pH in the range of from 5 to 8 and at a temperature in the range of 20.degree. C. to 40.degree. C.
