late (II) and AcONH4 affords 2,6-dinor-nifedipine (III) and minor amounts of 1,2-dihydropyridine (IV) instead of the previously proposed 2,5-dicarboxylate isomer of
(III), as proven by X-ray analysis. The oxidation product of (IV) is transformed into
benzonaphthyridine derivatives (VI)-(VIII). — (GOERLITZER*, K.; BODE, M.;
