Heterodiene synthesis

Transamination occurs in the reaction of amidines of benzoic and trichloro- and trifluoroacetic acids with azomethines obtained from aniline and various aromatic aldehydes; two molecules of the resulting benzylideneamidines react to give 1,2-dihydro-sym-triazines via the Diels-Alder scheme with the liberation of imino aldehydes.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 2, pp. 281–283, February, 1973.See [1] for communication IV.
