established by comparison of the 1H-NMR data of their MTPA esters with those of optically active model tetrahydrofurans. 12R, 15S, 16S, 19R, 20R, 23R, 24S configuration was assigned for squamostatins-B and -D, whereas 12R, 15S, 16S, 19R, 20R, 23R, 24R configuration was assigned for squamostatins-C and -E.
通过比较它们的MTPA酯与旋光模型四氢呋喃的MT酯的1 H-NMR数据,已经建立了不相邻的双-四氢呋喃产乙酸菌素的绝对立体化学。12 - [R,15小号,16小号,19 - [R 20 - [R,23 - [R,24小号配置被分配了用于squamostatins-B和-D,而12 [R,15小号,16小号,19 - [R 20 - [R 23 - [R ,为南瓜素-C和-E分配了24 R构型。
