including a Favorski-like ring contraction and amide oxidation by methanesulfonic acid, is presented. Detailed 1H and 13C assignments are made for many of the products, and ultraviolet absorption for seven steroidal enamides is tabled. Long-range homo- and heteronuclear NMR connectivities were used to confirm the structure of three dimeric compounds and to assign the configuration of the methoxy function of
