摘要

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 alpha-diazo-beta-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.
