Abstract

A Ni/photoredox dual-catalyzed multicomponent cross-electrophile coupling of N-vinyl amides with (hetero)aryl halides and (2°, 3°)-alkyl redox-active esters in the presence of cheap reductant Hantzsch ester is reported here. This reductive protocol provides direct access to various synthetically challenging chiral α-arylamides in good yields and excellent enantioselectivities (up to 99% ee, with the majority exceeding 97% ee), which can be further derived into chiral primary and secondary amines. Preliminary experimental studies shed light on the potential catalytic pathways.

期刊介绍： Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
