Title: “Enantioselective Organocatalytic Cyclopropanation of Enals using Benzyl Chlorides.”

Abstract:

Cyclopropanes are found in many natural products and have been shown to have a wide array of biological activities for insecticidal, antibiotic, antifungal, antitumor, and antiviral purposes. As such, they have become a focus for asymmetric chemists to develop methodologies yielding enantioenriched cyclopropanes. This has been done from a variety of approaches using chiral auxiliaries, chiral transition-metal complexes and organocatalytic methods. The cyclopropanation of enals using benzyl chlorides through an organocatalytic pathway utilizing chiral secondary amines is reported producing excellent  stereoselectivity.
