The synthesis of some C-nor-D-homopregnane and androstane derivatives from hecogenin is described. Hecogenin was degraded to III which in turn was converted to Va via IV. Manganesedioxideoxidation of Va yielded XVIIIa which was reduced to C-nor-D-homo-epiandrosterone (XXVa). This latter compound possesses the epiandrosterone configuration at each of the ring junctures.
