dc.description.abstractThe photolysis of 26-hydroxy-furostan (5) and (8) in the presence of Pb(OAc)4/I2 afforded spirostan sapogenins (4) and (7) respectively in 80% yield. This cyclization takes place by an uncommon 1,6-hydrogen shift involving a 7-membered transition state as demonstrated by using specifically deuterium labeled compounds.-
