An efficient one-pot synthesis of tetra-substituted pyrroles
摘要:
The three-component reaction of primary amines, dialkyl acetylenedicarboxylates and beta-nitrostyrene derivatives in the presence of Iron(III) chloride afforded 1,2,3,4-tetra-substituted pyrroles in high yields. These reactions could precede via domino Michael addition/cyclization process. (C) 2011 Elsevier Ltd. All rights reserved.
