Abstract

Synthesis of steroidal systems has been of special interest among synthetic chemists. Some methodologies have been developed for synthesis of steroid frameworks on the basis of intramolecular cyclization of o-quinodimethanes, generated by thermolysis of benzocyclobutene precursorsla-and thermal cheletropic elimination of SO2 from 1, 3- dihydrobenzo [c] thiophene 2, 2-dioxides. If* g In the previous paper2 we described a ...
