Organocatalytic Enantioselective Michael Addition of 3-Indolinone-2-Carboxylates to Maleimides
An organocatalyzed asymmetric conjugate addition of 2-substituted 3-indolinones to maleimides has been developed by using a chiral bifunctional squaramide derived from quinidine to promote the reaction. This method provides easy access to 3-indolinone-2-carboxylate-succinimide adducts in high yields with excellent diastero and entantioselectivities and is a useful approach for the construction of vicinal quaternary-tertiary chiral centers. In addition, product 4l was successfully converted into a chiral indoline-pyrrolidine adduct.
