A synthesis of 4-amino-1-azadienes 1 by addition of Zn-enolates of Schiff bases to nitriles is described.This method improves the yields achieved by the former one using AlCl3.Key words: Synthesis; 4-amino-1-azadienes; Zn-enolates.
Novel Synthesis of Di-imines by the Transformation of 1-Aryl-4,6-disubstituted Pyrimidin-2(1H)-ones

The di-imines (4), which are versatile starting materials for the synthesis of heterocycles, are obtained in fair yields when the 1-aryl-4,6-disubstituted pyrimidin-2(1H)-ones (3) are treated with alkoxide, both photochemically and thermally.The di-imines (4) thus obtained, when treated with disulphide, give the 1,3-thiazine-2-thiones (8) and/or the 1-arylpyrimidine-2(1H)-thiones (9).
