Abstract

The enantioselective preparation of the tricyclo[4.4.0.0^5,7]dec-2-ene derivatives via the catalytic asymmetric intramolecular cyclopropanation (CAIMCP) reactions of α-diazo-β-keto esters with excellent ee (95-98% ee) is described. The chiral building blocks reported herein would be versatile intermediates for enantioselective natural products synthesis.
