  Domino Cyclization of 2-Isothiocyanatobenzonitrile with Carboxylic Hydrazides − One-Pot Synthesis of 1,2,4-Triazolo[1,5-c]quinazoline-5(6H)-thiones

  摘要：

  One-pot reactions between carboxylic hydrazides and 2-isothiocyanatobenzonitrile afforded pharmacologically relevant 1,2,4-triazolo[1,5-c]quinazoline-5(6H)-thiones in good yields. These compounds were transformed into the corresponding amino-substituted derivatives in good yields in one or two steps. ((C) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003).
