Feruloylated mono- and di-acylglycerols were synthesized in a two step reaction: ethyl ferulate was first transesterified with glycerol and then this was esterified with oleic acid. The yield of the combined feruloylated mono- and di-acylglycerols in the second reaction reached 96% when esterification of 0.3 g transesterification products with 2.22 g oleic acid was catalyzed with 0.25 g Candida antarctica lipase at 60 degrees C under a vaccum of 10 mmHg for 1.33 h.
阿魏酸单酰甘油和二酰甘油通过两步反应合成
首先阿魏酸乙酯与甘油进行酯交换反应，然后再与油酸进行酯化反应。当0.3 g酯交换反应产物与2.22 g油酸在0.25 g南极假丝酵母脂肪酶催化下，于60℃、10 mmHg真空条件下反应1.33 h时，第二步反应中阿魏酸单酰甘油和二酰甘油的总产率达到96%。
