Isothiourea‐Catalyzed Functionalization of Pyrrolyl‐ and Indolylacetic Acid: Enantioselective Synthesis of Dihydropyridinones and One‐pot Synthesis of Pyridinones Open
A protocol for the isothiourea‐catalyzed enantioselective functionalization of pyrrolyl‐ and indolylacetic acids has been developed. Stereodefined dihydropyridinones are accessed through formal [4+2] cycloaddition of an in situ generated i…
