The synthesis and application of new axially chiral skeletons have always been an attractive and important topic in synthetic chemistry. Herein, we developed a Pd(II)-catalyzed atroposelective C-H olefination for the synthesis of axially chiral styrene with N,N-disubstituted amide groups. A broad range of axially chiral styrenes were obtained in good to excellent yields and enantioselectivities (up to 80% yield and 95% ee) under mild conditions. Gram-scale reaction and further transformation reactions also provide a platform for synthetic applications of this method.
