✦ Synopsis

Although enamines are known to be excellent addends in many Michael type reactions, the reaction of enamines with Schiff bases has hitherto never been found in the literatures. We now would like to report the reaction and its stereochemical consequence.

Reaction of 1-morpholino-l-cyclohexene (Ia) or 1-morpholino-4-tert.-butyl-I-cyclohexene (Ib) with benzylideneaniline (II) was carried out at room temperature by standing overnight in absolute methanol. Substituted enamines (IIIa,b) were obtained (yield; about 30%) whose structures were confirmed by elementary
