A process for irreversible regio- and stereoselective enzyme catalyzed acylation of alcohols using enol esters as acylating reagents is disclosed. The present invention permits the selective modification of hydroxyl group(s) of chiral and meso alcohols, including sugars, organometallics, and glycosides. The enol freed upon transesterification rapidly tautomerizes to the corresponding volatile aldehyde or ketone thereby preventing the reverse reaction from occurring.
本发明公开了一种使用烯醇酯作为酰化试剂的不可逆区域和立体选择性酶催化醇酰化工艺。本发明可以选择性地修饰手性醇和中性醇(包括糖、有机
金属和苷类)的羟基。酯交换反应后释放出的烯醇会迅速同分异构成相应的挥发性醛或酮,从而防止发生逆反应。
