reactivity switch of 3-methyl-2-vinylindoles, which has not been reported before. This reaction also represents the first catalytic asymmetricarylativedearomatization of vinylindoles, which will help confront the challenges in catalytic asymmetricarylativedearomatization and dearomatization of vinylindoles.

The first catalytic asymmetric [3+2] cyclization of quinone monoimides with olefins has been established, which employed 3-vinylindoles as a class of competent olefins and spiro-chiral phosphoric acid as a powerful...
A formal [3 + 3] cyclization reaction of 2-indolylmethanols with quinones was realized to furnish indole-fused scaffolds in moderate to excellent yields. This protocol was proceeded smoothly under acid condition, with high high yields and broad substrate scope.
