title: Solution-phase parallel synthesis of 3,5,6-substituted indolin-2-ones.
abstract: A practical and efficient new parallel method has been developed for the synthesis of 3-substituted indolin-2-ones with a large variety of substituents at the 5- and 6-positions using 1,5-difluoro-2,4-dinitrobenzene. This 3,5,6-substituted indolin-2-one skeleton possesses three points of diversification and, thus, affords new opportunities for identification and optimization of leads in drug discovery.
