(+/-)-3-oxovincadifformine ethyl ester 14 has been synthesized through an intramolecular <4? + 2?> cycloaddition of the 3-oxosecodine 13 first prepared in turn from the enamide 10 by dehydrogenation with benzeneseleninic anhydride.An insight into the conversion of 10 into 13 was gained, resulting in the suggestion of a plausible mechanistic pathway.
