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.
亚环戊二烯-或亚环己基丙二腈、氰基乙酸酰胺或硫代酰胺和烷基化剂的多组分缩合得到4-螺环戊烷-和4-螺环己烷烟酸腈和酰胺。通过 X 射线衍射确定了几种反应产物的结构。
