Abstract

An enantioselective addition of enamides to cyclic ketimines generated in situ from 3‐hydroxyisoindolin‐1‐ones was developed. This reaction takes advantage of readily available substrates, mild reaction conditions, as well as enlarged reaction generality, affording chiral 3,3‐disubstituted isoindolin‐1‐ones with a quaternary stereogenic center in high yields (up to 98%) and enantioselectivities (up to 99% ee).

Abstract

The method tolerates a variety of aryl, hetaryl, and alkyl β-keto acids and furnishes the desired 3-functionalized 3-indolyloxindoles with an all-quaternary stereocenter in high yields and enantioselectivities. [ABSTRACT FROM AUTHOR]
