The preparation of 11,12,13,14,16,17-hexahydro-15H-cyclopenta[a]phenanthren-11,17-dione has been optimised, and the derived 17,17-ethylene diketal has been employed in the synthesis of the bay-region 11-trifluoromethyl-, 11-cyano-, and 11-amino-15,16-dihydrocyclopenta[a]phenanthren-17-ones.
优化了11,12,13,14,16,17-hexahydro-15 H -cyclopenta [ a ] phenanthren-11,17-dione的制备方法,并将所得的17,17-乙烯二缩酮用于合成湾区11-三氟甲基-,11-氰基-和11-氨基-15,16-二氢环戊基[ a ]菲蒽-17-的结构。
