Synthesis of heterocycles using products of the addition of polyhaloalkanes to unsaturated systems. 5. Synthesis of substituted thiazoles

First syntheses are reported for 2-aminothiazoles, 2-chlorothiazoles, and 2-thiazolones with a 2,2,-trichloroethyl group at C₍₅₎ using the products of the homolytic addition of CCl₄ and trichloroacetonitrile to methyl vinyl ketone. Further transformation of this substituent may be carried out for the preparation of compounds with possible biological activity.For communication 4, see [1].Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 8, pp. 1120–1124, August, 1993.
