title: Synthesis of chiral chalcone derivatives catalyzed by the chiral cinchona alkaloid squaramide.
abstract: An effective method has been developed for the preparation of novel chiral chalcone derivatives under mild conditions from the easily accessible starting materials nitromethane and chalcone derivatives 2. The corresponding products were obtained in moderate yields with excellent enantioselectivities (up to 99%).
