  Switchable selectivity in multicomponent heterocyclizations of acetoacetamides, aldehydes, and 3-amino-1,2,4-triazoles/5-aminopyrazoles

  摘要：

  Multicomponent heterocyclizations of 3-amino-1,2,4-triazoles/5-aminopyrazoles with acetoacetamides and aromatic aldehydes were studied in detail using conventional thermal heating, ultrasonication, and microwave irradiation. Several different synthetic pathways for these cyclocondensations occurring under either kinetic or thermodynamic control were established depending on the temperature regime and building block selection. The experimental data obtained and the procedures developed allow tuning selectivity of the multicomponent reactions studied. (C) 2011 Elsevier Ltd. All rights reserved.
