A convenient method for transforming 3-acyl-sn-glycerols into 1-acyl-2,3-diacyl'-sn-glycerols, antipodes of 1,2-diacyl'=3-acyl-sn-glycerols, of relatively high optical purity, via the 1,2-dimesyl-3-acyl-sn-glycerols has been worked out. ORD and CD curves of optically active triglycerides and also some mono- and diglycerides have been studied in detail. The curo 200 nm or below. A Cotton effect from the n yeilds ets* transtition of the ester chromophore was observed at 215-220 nm, which was negative for triglyceritical rotations could be observed in triglycerides with very small differences in chain length, such as 1,2-dilauroyl-3-myristoyl-sn-glycerol.
已经研究出一种便捷的方法，可通过1,2 - 二甲磺酰基 - 3 - 酰基 - sn - 甘油将3 - 酰基 - sn - 甘油转化为1 - 酰基 - 2,3 - 二酰基'- sn - 甘油，即1,2 - 二酰基'= 3 - 酰基 - sn - 甘油的对映体，且具有较高的光学纯度。已详细研究了光学活性甘油三酯以及一些甘油单酯和甘油二酯的ORD和CD曲线。在200nm及以下的曲线。在215 - 220nm处观察到酯发色团的n→π跃迁产生的科顿效应，对于链长差异非常小的甘油三酯，如1,2 - 二月桂酰基 - 3 - 肉豆蔻酰基 - sn - 甘油，其甘油三酯的旋光性为负。 （注：原文存在一些拼写错误，如“curo”应改为“curve”，“yeilds”应改为“yields”，“ets”应改为“π*” ，翻译时尽量按正确理解翻译，但原文错误可能会影响译文的准确性和流畅性。）
