Article abstract of DOI:10.1016/0039-128X(94)90024-8

An efficient approach to 17-chloro-16(17) unsaturated D-homo antiprogestins is described.The key steps of the synthesis are a ring-expansion via dichlorocarbene addition to a 17-silyl enol ether and a palladium catalyzed coupling of an 11β-(4-aryltriflate
