摘要
(Chemical Equation Presented) Improving with time: The first catalytic asymmetric synthesis of chiral 1,3-disubstituted isoindolines is based on a Brønsted acid catalyzed one-pot reaction consisting of a Friedel-Crafts reaction and a base-catalyzed aza-Michael addition (see scheme). The enantiomeric ratio of the product significantly increases with reaction time as a result of a Brønsted acid catalyzed stereoablative kinetic resolution, which occurs in tandem to the first step. © 2008 Wiley-VCH Verlag GmbH & Co.
