摘要:
A chiral amide-phosphine bifunctional catalyst was developed and successfully applied to the asymmetric intermolecular cross-vinylogous Rauhut-Currier of alkyl vinyl ketones with para-quinone methides, offering excellent regioselectivity and stereoselectivity (up to >99% enantiomeric excess (ee)). This method provides a facile access to structurally diverse widely existed diarylmethine stereogenic centers with excellent enantioselectivity. Density functional theory (DFT) calculations have been performed to understand the mechanism and enantioselectivity for this phosphinecatalyzed asymmetric transformation.
