Organocatalytic asymmetric synthesis of 3-amino-2-oxindole derivatives bearing a tetra-substituted stereocenter

3-Amino-2-oxindoles bearing tetra-substituted stereocenter are very important constituents of many bioactive and pharmaceutical agents. In the last few years, asymmetric organocatalysis emerged as an excellent approach for the synthesis of optically active 3-substituted-3-amino-2-oxindoles. This review describes the various organocatalytic enantioselective strategies for the synthesis of 3-substituted 3-amino-2-oxindole frameworks. (c) 2013 Elsevier Ltd. All rights reserved.
