Solasodine 1, the aglycon of solasonine and solamargine with the antitumour activity isolated from Chinese medicinal herb “Long Kui” Solalum nigrum l., was synthesized by utilizing the intact skeleton of diosgenin in 9 steps and in 21% overall yield. The key reaction in the synthesis involved a new bromination-E/F ring-opening reaction of 16-hydroxy-steroidal sapogenins.

Key words: Solasodine, diosgenin, steroidal alkaline; Solalum Nigrum L
