Molybdenum hexacarbonyl mediated synthesis of indolin-2-one & azaindolin-2-one under catalyst free conditions
摘要:
Syntheses of indolin-2-ones and azaindolin-2-ones have been realized. The strategy involves the formation of tosylhydrazone from tosylhydrazine and 2-amino aryl or pyridyl aldehydes/ketones which then undergo intramolecular aminocarbonylation to afford indolin-2-ones and azaindolin-2-ones. The generality of the method was demonstrated by synthesizing C3 substituted and unsubstituted indolin-2-one and azaindolin-2-one derivatives. (C) 2015 Elsevier Ltd. All rights reserved.
