Synthesis of Demissidine Analogues from Tigogenin via Imine Intermediates
A five-step transformation of a spiroketal side chain of tigogenin into an indolizidine system present in solanidane alkaloids such as demissidine and solanidine was elaborated. The key intermediate in the synthesis was spiroimine <b>3</b> readily obtained from tigogenin by its RuO<su...
