PREPARATION OF GLYCEROL DERIVATIVES AND INTERMEDIATES THEREFOR
摘要
<p>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<SUB>1</SUB> -2-R<SUB>2</SUB> - 3-acetyl-glycerol derivative comprises the steps of: obtaining 1-R<SUB>1</SUB> -3-protecting group-glycerol by introducing a protecting group to 3-position of 1-R<SUB>1</SUB> -glycerol; obtaining 1-R<SUB>1</SUB> -2-R<SUB>2</SUB> - 3-protecting group-glycerol by introducing R<SUB>2</SUB> group into 2-position of 1-R<SUB>1</SUB> -3-protecting group- glycerol; and carrying out the deprotection reaction and the acetylation reaction of 1-R<SUB>1</SUB> -2-R<SUB>2</SUB> - 3-protecting group-glycerol at the same time. Wherein, R<SUB>1</SUB> and R<SUB>2</SUB> 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.</p>
