摘要:
An organocatalytic enantioselective N-nitroso-aldol reaction of 2-oxindoles promoted by a cinchona alkaloid catalyst has been developed. The reaction shows exclusively N-selectivity, affording corresponding products with good to excellent yields (up to 100%) and moderate enantioselectivity. The regioselectivity of nitroso-aldol reaction being controlled by different cinchona catalysts was also observed. (C) 2010 Elsevier Ltd. All rights reserved.
