Regioselective synthesis of 6-benzylthiazolo[3,2-b]1,2,4-triazoles during Sonogashira coupling
摘要:
The reaction of 3-merciptopropargyl-1,2,4-ti-iazoles with various iodobenzenes catalyzed by Pd-Cu leads to the regioselective formation of 6-beiizyltliiazolo[3,2-b]1,2,4-triazoles 4. The structure of 4d was confirmed by X-ray analysis. (C) 2005 Elsevier Ltd. All rights reserved.
