higher yields compared with the conventional method. The Mannich bases with a cyclic amine part show in the dehydrogenation, using mercury-EDTA, a neighbouringgroup participation of the oxime in type 4 and of the oxime or amide function in 12 yielding cyclized products. For the reaction a plausible mechanism is proposed.
