摘要
An efficient and enantioselective route toward an architecturally unusual ergostane-type steroid, dankasterone B, is presented. The cis-decalin skeleton of the steroid was established by an intramolecular metal-catalyzed hydrogen atom transfer (MHAT) reaction. A radical rearrangement was used to construct the 13(14 -> 8)abeo-ergostane skeleton.
