Article Abstract

Rh(III)-catalyzed direct oxidative C-H/C-H cross-coupling between -pyrimidylindoles and β-ketoesters is presented. Easily available β-ketoesters are used as an alkylating agent for the facile construction of all-carbon quaternary centers under mild conditions. The ester group in the product can undergo decarboxylation or decarboxylative amination.
