Babiy S. Novel Transformations of Arylsulfonyl Substituted Enamides and Related Reagents into Derivatives of Azaheterocycles

N-(1-Arylsulfonyl-2,2-dichloroethenyl)amides, sulfur containing enimidoylchlorides and enheterocumulenes. The study of novel cyclocondensations on the basis of arylsulfonyl substituted enamides and related reagents resulting in unknown derivatives of nitrogencontaining heterocycles. IR, NMR spectroscopys, X-ray diffraction analysis, chromatography. Accessible arylsulfonyl substituted enamides as well as appropriate sulfur containing enimidoylchlorides, enisonitriles, and enheterocumulenes by the simple methods turnout to new types of oxazole, thiazole, imidazole, and quinazoline derivatives. A cyclization of 1-tosyl-2,2-dichloroethenylisothiocyanate with various nucleophiles is the irreplaceable approach to a great number of trifunctionalized thiazoles. Interaction of some 4-tosyl-5-chloro-1,3- thiazole derivatives with thiophenoles proceeds through elimination chlorine and toluolsulfynate-anions. The scope of application - Organic chemistry, Bioorganic chemistry.
