摘要：

An efficient N-heterocvclic carbene (NHC)-catalyzed "Michael-Michael-Lactonization" cascade process involving chalcone derivatives and alpha-bromoenals for the syntheses of functionalized naphthopyranones was disclosed. This approach was qualified with good yields, readily available starting materials and mild reaction conditions.
