New methods of synthesis, structure and aminomethylation of 4-imino-2-(dicyanomethylene)-3-azaspiro[5.5]undecane-1,5-dicarbonitrile

Sequential reaction of cyclohexanone with malononitrile and2-aminopropene-1,1,3-tricarbonitrile in the presence of potassium hydroxide orsodium ethylate in ethanol gave4-imino-2-(dicyanomethylene)-3-azaspiro[5.5]undecane-1,5-dicarbonitrile. Thelatter reacted with primary amines and an excess of form...
