Various triglycerides have been prepared by the acylation of either cis-1,3-O-benzylideneglycerol or 2,3-O-isopropylideneglycerol, followed by removal of the protecting group and acylation of the resultant diol. Alternatively, acylation of dihydroxyacetone, reduction of the intermediate ketone with sodium cyanoborohydride (pH 4) and acylation of the resultant alcohol also provide triglycerides in good yields. In some of these esters of glycerol, 13C n.m.r . spectroscopy (125.7 MHz) was used to monitor potential acyl migration. Finally, 2-halopyridinium salts were investigated as an alternative to the normal dicyclohexylcarbodiimide/dimethylaminopyridine couple for glycerol esterification.
通过对顺式-1,3-O-亚苄基甘油或 2,3-O-亚异丙基甘油进行酰化,然后去除保护基团并对生成的二元醇进行酰化,可以制备出各种甘油三酯。另外,二羟基丙酮的酰化、中间酮与氰基硼氢化钠(pH 值为 4)的还原以及由此产生的醇的酰化也能以良好的收率提供甘油三酯。在其中一些甘油酯中,13C n.m.r .光谱(125.7 MHz)被用来监测潜在的酰基迁移。最后,研究人员还研究了 2-卤代吡啶鎓盐,以替代用于甘油酯化的普通二环己基碳二亚胺/二甲基氨基吡啶偶联物。
