Reaction of 3-Phenyl-5-aminopyrazole with Carbon Disulfide: A Novel Synthesis of 3-(3'-Phenylpyrazol-5'-yl)-4-phenylpyrazol-2-thione as well as of Pyrazolothiazole and Pyranothiazole Derivatives

3-Phenyl-5-aminopyrazole (1) reacts with carbon disulfide, followed by in situ reaction with α-haloketones 3a-c, to afford 5, 7a, and 7b, respectively.Compounds 5 and 7 were further utilized for the formation of heterocycles and their fused derivatives. - Keywords: Aminopyrazole; Pyrazolothiazole; Pyranothiazole
