compounds. Using a catalytic modular approach, 31 new 3-amino-3-aryl-2-oxindoles were prepared by a simple Rh-catalysed addition of arylboronic acids to isatin-derived N-Boc-protected ketimines (Boc = tert-butoxycarbonyl). A low catalyst loading of 3 mol-% was used, and the reaction showed a wide scope with high functional-group compatibility, and gave good yields. We report the first catalytic enantioselective
