The multicomponent condensation of cyclopentylidene- or cyclohexylidenemalononitrile, cyanoacetic acid amides or thioamides, and alkylating agents affords 4-spirocyclopentane- and 4-spirocyclohexanenicotinic acid nitriles and amides. The structures of several reaction products were determined by X-ray diffraction.Изучена многокомпонентная конденсация циклопентилиден, циклогексилиденмалононитрила, амидов или тиоамидов цианоуксусной кислоты и алкилирующих реагентов, которая приводит к образованию нитрилов и амидов 4-спироциклопентан- и 4-спироциклогексанникотиновой кислоты. Строение нескольких полученных продуктов изучено методом РСА
