Synthesis of tetrasubstituted pyrroles by palladium-catalyzed cyclization of propargylic carbonates with β-enamino esters
摘要:
The reaction of propargylic carbonates with beta-enamino esters in the presence of palladium catalyst is described. Various tetrasubstituted pyrroles were regioselectively synthesized via a successive nucleophilic cyclization. (c) 2013 Elsevier Ltd. All rights reserved.
