摘要:
We report here the use of the readily accessible ethyl-2-(2-chloroethyl)acrylate as a new very versatile alpha-cyclopropylester cation synthon, which reacts efficiently and selectively with carbon-, nitrogen-, sulfur- or phosphorus-centered nucleophiles through Michael addition followed by intramolecular capture of the incipient ester enolate to afford funtionalized cyclopropane esters in high yields.
