摘要：

Revised structures are proposed for four adducts of ergosteryl acetate and maleic anhydride. One is a normal Diels-Alder adduct of endo configuration, in which the dienophilic addition has occurred from the α side. The other three adducts are produced by an addition-abstraction process, with addition at C-7 and concomitant abstraction of either the 9α or the 14α hydrogen to give 7α succinic anhydride derivatives of 3β-acetoxy-ergosta-5,8,22-triene and 3β-acetoxyergosta-5,8(14),22-triene. © 1977.
