A diastereomeric mixture at C-3 of panaxytriol (1) was synthesized starting from L-(+)-diethyl tartrate, and the absolute configurations at C-9 and C-10 of 1 were confirmed to be 9S and 10S, respectively. The absolute configuration at C-3 of 1 was reconfirmed to be R by the application of Mosher's method.
以L-(+)-酒石酸二乙酯为原料,合成了人参三醇(1)的C-3位非对映异构体混合物,并证实1的C-9位和C-10位绝对构型分别为9S和10S。应用Mosher方法再次确认1的C-3位点的绝对构型为R。
