The First Enantioselective Organocatalytic Mukaiyama—Michael Reaction: A Direct Method for the Synthesis of Enantioenriched γ-Butenolide Architecture.
摘要:
Discloses that iminium organocatalysts using chiral imidazolidinones provide the first enantioselective Mukaiyama-Michael reaction with simple unsaturated aldehydes. Importance of the complementary mechanistic function of LUMO-lowering iminium and metal catalysis and the chemical utility of enantioselective organocatalysts; Provision of nonconventional chemoselectivity by amine catalysis.
