Abstract:
Methine and isomethine bases and bismethine compounds can be derived together from the treatment of excess diazomethane on quaternary aporphine alkaloids. The result of this reaction can be described as the E2 mechanism. Heat treatment of aporphine N-oxides produces Cope elimination and forms phenanthrene hydroxylamine derivatives. The biogenetic pathway from aporphines to phenanthrenes can be elucidated by this reaction.
