    摘要: PURPOSE:To obtain a new aphidicolan derivative having antitumor action and having a mercapto group as a substituent group at 17-position and its synthetic intermediate. CONSTITUTION:3alpha, 16beta, 18-Trihydroxy-17-mercaptoaphidicolan of formula I, 16beta-hydroxy-17-mercapto-3alpha, 18-epoxyaphidicolan of formula II and 3alpha, 18, 16beta, 17-diepoxyaphidicolan of formula III. The compound of formula I is obtained by treating 3alpha, 16beta, 18-trihydroxy-17-p-toluenesulfonyloxyaphidicolan with a basic substance and reacting the resultant 3alpha, 18-dihydroxy-16beta, 17- epoxyaphidicolan of formula IV with an alkali metal hydrosulfide. The compound of formula II is obtained by treating 3alpha, 16beta-dihydroxy-17, 18-bis(p- toluenesulfonyloxy)aphidicolan with a basic substance to afford a compound of formula III and then reacting the compound of formula III with an alkali metal hydrosulfide.
