  The object of the present invention is a novel and simple process for the production of 1,2-diacyl-sn-glycerols, wherein the acyl groups may be the same or different. According to the invention D-mannitol is reacted with benzene boronic acid or a derivative thereof to form a D-mannitol-monobenzeneboronate which compound is acylated either to form, after removal of the benzeneboronate protective group, a 1,2,5,6-tetraacyl-D-mannitol with four identical acyl groups, or is acylated selectively in two stages, by first acylating the 1,6-hydroxy groups of the boronate protected D-mannitol to form, after removal of the boronate protection, a 1,6-diacyl-D-mannitol, which then is repeatedly reacted with a benzene boronic acid or a derivative thereof and then acylated in the 2- and 5-positions. After removal of the boronate protective group, the tetra-acylated D-mannitol obtained either in the one-stage or two-stage process is split by oxidation to form a 1,2-diacyl-glyceraldehyde which in turn is reduced to the corresponding 1,2-diacyl-sn-glycerol. By means of the invention it is thus possible to prepare 1,2-diacyl-sn-glycerols in which the acyl groups can be the same or different.

  本发明的目标是一种新颖且简单的生产1,2-二酰基-sn-甘油的方法，其中酰基可以相同或不同。根据本发明，D-甘露醇与苯基硼酸或其衍生物反应，形成D-甘露醇-单苯基硼酸酯，该化合物被酰化，形成去除苯基硼酸保护基后的1,2,5,6-四酰基-D-甘露醇，具有四个相同的酰基，或者被选择性地分两个阶段酰化，首先酰化硼酸保护的D-甘露醇的1,6-羟基，形成去除硼酸保护后的1,6-二酰基-D-甘露醇，然后反复与苯基硼酸或其衍生物反应，并在2-和5-位置酰化。去除硼酸保护基后，通过氧化将一阶段或两阶段过程中获得的四酰基D-甘露醇分解成1,2-二酰基甘油醛，然后还原为相应的1,2-二酰基-sn-甘油。通过本发明，因此可以制备出酰基可以相同或不同的1,2-二酰基-sn-甘油。
