Asymmetric synthesis of tri- and tetrasubstituted trifluoromethyl dihydropyranones from alpha-aroyloxyaldehydes via NHC redox catalysis
Abstract
The asymmetric synthesis of tri- and tetrasubstituted trifluoromethyl dihydropyranones via an NHC-catalyzed redox process, introducing methyl, benzyl, and aryl substituents to the C(5) position, is presented. Their substrate-controlled derivatization into δ-lactones and cyclic hemiacetals containing stereogenic trifluoromethyl groups is also described.
