Disclosed is a process for the regioselective preparation of glycerol derivative in a high efficiency and yield. The process for the regioselective preparation of 1-R
1
-2-R
2
-3-acetyl-glycerol derivative comprises the steps of: obtaining 1-R
1
-3-protecting group-glycerol by introducing a protecting group to 3-position of 1-R
1
-glycerol; obtaining 1-R
1
-2-R
2
-3-protecting group-glycerol by introducing R
2
group into 2-position of 1-R
1
-3-protecting group-glycerol; and carrying out the deprotection reaction and the acetylation reaction of 1-R
1
-2-R
2
-3-protecting group-glycerol at the same time. Wherein, R
1
and R
2
are fatty acid groups having 16 to 22 carbon atoms, and are different from each other; and the protecting group is trityl group or trialkylsilyl group.

甘油衍
生物的过程。制备1-R1-2-R2-3-乙酰基
甘油衍
生物的选择性区域制备过程包括以下步骤:通过在1-R1-
甘油的3位引入保护基获得1-R1-3-保护基-
甘油;通过在1-R1-3-保护基-
甘油的2位引入R2基获得1-R1-2-R2-3-保护基-
甘油;同时进行1-R1-2-R2-3-保护基-
