Synthesis of 4-tosyl-5-chloro-1,3-thiazole-2-carbonitrile and its transformations
摘要:
Reaction of the available 1-tosyl-2,2-dichloroethenyl isothiocyanate with sodium cyanide yields new clearly electrophilic substrate of thiazole nature containing the nitrile group, the tosyl residue, and the chlorine atom at C(2), C(4), and C(5) respectively. The direction of the reaction of this substrate with nucleophile depends significantly on the nature of the latter. It was used in regioselective syntheses of a series of the unknown previously trifunctional thiazoles.
