摘要：

The orthoesters, 4a and 4b were obtained from treatment of methyl-7,13E-labdadien-17-oate, 3, under Sharpless asymmetric epoxidation conditions . The hydrolysis followed by dehydration of the orthoesters led to the synthesis of two new diterpenic acids isolated from Halimium viscosum : 14R,15-dihydroxy-7,13(16)-labdadien-17-oic and 14S,15.dihydroxy-7, 13(16)-labdadien-17-oic. © 1990.
