Reaction of 2-acylamino-3,3-dichloroacrylonitriles with 2-aminothiophenol
摘要:
Reactions of 2-acylamino-3,3-dichloroacrylonitriles with 2-aminothiophenol in the presence of triethylamine was shown to lead to 2-aryl-3,3-bis(2-aminophenylsulfanyl)acrylonitrile, which suffered a transformation into 5-amino-4-(benzothiazol-2-yl)oxazole derivatives at heating without solvent. The formation of the same compounds from these reagents proceeded in one step in the presence of N,N-dimethylaniline. The presence of primary amino groups in the derivatives of 5-aminooxazole was confirmed by acylation and further transformation, which was used also for indroduction of various biophoric sites in 5 position of the oxazole ring.
