Synthesis of polysubstituted pyrroles from sulfinimines (N-sulfinyl imines)
摘要:
Polysubstituted 2-carboxylate and 2-phosphonate pyrroles are prepared by aromatization of the corresponding 3-oxo 2-carboxylate and 2-phosphonate NH-pyrrolidines using air. Reaction of electrophiles with 3-oxo pyrrolidine dianions readily introduces substituents, regioselectively at C-4 in these pyrrolidines. (c) 2008 Elsevier Ltd. All rights reserved.
