Abstract

Abstract The enaminoester 1-benzyl-2-ethoxycarbonylmethyleneimidazolidine reacts with α, β-enones and other Michael acceptors to give 1, 4-adducts; removal of the ethoxycarbonyl group completes overall conjugate addition of the imidazoline α-anion (which itself adds 1, 2 to enones), and hydrolysis affords carboxylic acids.
