Spirocephams 4 and S have been obtained from aldehyde 1 and hydroxylamine or hydrazine, as single diastereoisomers. Structures of these compounds have been elucidated by NME experiments and FIND0 calculations. In the course of a prograssne to design cephems modified at the 3 position, we condensed
Papaverine is a drug that can be easily oxidized to papaverinol, papaveraldine and to recently discovered 2,3,9,10-tetramethoxy-12-oxo-12H-indolo[2,1-a]isoquinolinium chloride. In a strong alkaline medium the spectroscopic properties of this latter compound are modified indicating formation of a new
