Lipase-Catalyzed Resolution of Ibuprofen
摘要:
The resolution of ibuprofen by transesterification of its corresponding vinylester using lipase B from Candida antarctica is described. Compared to transesterification or hydrolysis of the ibuprofen ethyl ester (E < 2, 28-48 h), the reaction with vinylesters occurred significantly faster (1.5-5 h) and with considerably higher enantioselectivity (E = 8-39).
