octadecanal dimethyl acetal and D-(glycerol 1,2-carbonate) gave octadecanal di-D-(glycerol 1,2-carbonate) acetal which was converted into 3-O-(1-chlorooctadecyl)-D-glycerol 1,2-carbonate by the action of acetyl chloride at room temperature. The chloro-ether was treated with triethylamine to give a mixture of the cis- and trans-isomers of 3-O-octadec-1′-enyl-D-glycerol 1,2-carbonate in which the cis isomer
十八烷基二甲基乙缩醛与D-(甘油1,2-碳酸甘油酯)之间的交换反应得到十八烷基二-D-(甘油1,2-碳酸甘油酯)缩醛,其被转化为3 - O-(1-氯十八烷基)-D-甘油在室温下由乙酰氯作用生成1,2-碳酸根。用三乙胺处理氯醚,得到其中顺式异构体占优势的3 - O-十八烷基-1'-烯基-D-甘油1,2-碳酸酯的顺式和反式异构体的混合物。碳酸盐的碱性水解得到1- O的顺式和反式异构体的混合物-十八烷基-1'-烯基-L-甘油,其在吡啶中用乙酸酐或十六烷酰氯酰化,得到二乙酸酯或二棕榈酸酯。在硅胶-硝酸银板上通过薄层色谱分离二乙酸酯和二棕榈酸酯的顺式和反式异构体。双乙酸酯的顺式异构体的碱水解得到标题化合物。
