1-acyl-2-lyso-glycerophosphocholines. The reaction is effective using C-2 to C-16 acid chlorides in 2-propanol. After solvent replacement the lyso-phospholipid (lyso-PL) is subjected to a second acylation using acid anhydrides in methylene chloride. A series of 1(2)-short-2(1)-long-diacyl-glycerophosphocholines are obtained in high yields and selectivity. No diacylation product was detected. In order to detect
甘油磷酰胆碱(GPC)被转化为环状亚锡衍生物,其选择性地被酰化为1-酰基-2-溶血甘油磷酸胆碱。使用2-丙醇中的C-2至C-16酰氯,该反应有效。更换溶剂后,使用酸酐的二氯甲烷溶液对溶血磷脂(lyso-PL)进行第二次酰化反应。以高收率和选择性获得了一系列的1(2)-短-2(1)-长二酰基-甘油磷酸胆碱。未检测到二酰化产物。为了检测具有酰基链的反向排列的混合链脂质,首先引入长链,然后通过NMR比较由此得到的异构体化合物。为了确定异构体化合物的位置纯度,开发了NMR方法。
