Аннотация

The condensation of malononitrile with unsymmetrical dienones of the cyclohexane series under basic conditions selectively afforded substituted tetrahydroquinolinecarbonitriles. The reaction of 2,6-bis-(3-nitrophenylmethylidene)cyclohexan-1-one with malononitrile under similar conditions led to the formation of substituted tetrahydrochromenecarbonitrile. Factors determining the reaction direction and selectivity were discussed. The structure of the newly synthesized compounds was confirmed by IR and 1H NMR spectra.
