  Highly enantioselective synthesis of α-trichloromethyldihydropyrans catalyzed by bifunctional organocatalysts

  摘要：

  The enantioselective Michael addition of alpha-cyanoketones to alpha,beta-unsaturated trichloromethyl ketones was firstly reported. With a phenylalanine-derived bifunctional piperazine/thiourea catalyst, a series of alpha-trichloromethyldihydropyrans were obtained with up to 95% ee and 99% yield. (C) 2011 Elsevier Ltd.
