IMINE–ENAMINE TAUTOMERISM OF DIHYDROAZOLOPYRIMIDINES. 6. SYNTHESIS AND TAUTOMERISM OF THIENYL DERIVATIVES OF DIHYDRO-1,2,4-TRIAZOLO[1,5-<i>a</i>]PYRIMIDINES

Abstract

The cyclocondensation of thiophene analogs of chalcone with 3-amino-1,2,4-triazole gives 5- and 7-(α-thienyl)dihydro-1,2,4-triazolo[1,5-a]pyrimidines. The tautomer composition of synthesized compounds was analyzed.
