摘要：
The natural cycloartane triterpenoid cycloasalgenin, which is 20R,24S-epoxycycloartan-3 beta,6 alpha,25-triol-16-one, was partially synthesized in three steps starting from cyclosiversigenin. In addition to the desired product, its 17-epimer was synthesized. The analogous 17-epimer was also prepared from cycloadsurgenin.
