CYCLIZATION OF NITRILES XLII.SYNTHESIS, STRUCTURE AND STEREODEGENERATE TRANSFORMATION OF 1-AMINO-5-ARYL-2,6,6-TRICYANO-3-CYCLOPROPYL-1,3-CYCLOHEXADIENES

Sharanin, Yu. A.,Khoroshilov, G.E.,Shestopalov, A.M.,Nesterov, V.N.,Shklover, V.E.,Litvinov, V.P.

, p. 253 - 264 (2007/10/02)

The reaction of arylmethylenemalononitriles with (1-cyclopropylethylidene)malononitrile leads to 5-aryl-3-imino-2,4,4-tricyano-1-cyclopropyl-1-cyclohexanes, which are converted as a result of 1,5-sigmatropic rearangement into 1-amino-5-aryl-2,6,6-tricyano
