Abstract

original image

Water is out, aryl is in! Asymmetric synthesis of isoindoline-1-ones bearing an α-triaryl-substituted stereogenic center was realized in the enantioselective addition of arylboroxines to 3-aryl-3-hydroxyisoindolin-1-ones in the presence of a hydroxorhodium/chiral diene catalyst, where cyclic N-carbonyl ketimines were generated in situ by dehydration.
