title: Enantioselective N-heterocyclic carbene-catalyzed synthesis of indenopyrones.
abstract: The chiral N-heterocyclic carbene-catalyzed [4 + 2] cyclization of α-chloroaldehydes and arylidene indanediones was developed, giving the corresponding indenopyrones in good yields with high diastereoselectivities and enantioselectivities.
