Synthesis of polysubstituted dihydropyrroles and pyrroles from β-carbonyl O-methyloximes
摘要:
Polysubstituted 4,5-dihydropyrroles and pyrroles were synthesized from beta-carbonyl O-methyloximes via alkylation and intramolecular Michael addition with unsaturated 4-bromobutyrates by treatment with sodium hydride or a sodium alkoxide. (C) 2004 Elsevier Ltd. All rights reserved.
