Popis: | 1-Substituted 4-arylsulfonyl-5-aminopyrazoles were obtained by condensation of 2-arylsulfonyl-2-cyanovinyl ethyl ethers with hydrazine or its derivatives (phenylhydrazine and semicarbazide); condensation with hydroxylamine gave 4-arylsulfonyl-5-aminoisoxazoles, and condensation with thiourea gave 2-thioxo-4-amino-5-arylsulfonyl-1,2-dihydropyrimidines. |
