Straightforward Method

A straightforward method for the synthesis of indolin-3-ones bearing a C2-quaternary functionality is reported. This cross-coupling reaction allows the facile synthesis of a series of 2,2-disubstituted indolin-3-ones in the absence of a metal catalyst in up to 94% yields.

Cross Coupling Reaction

A short and facile synthesis of a series of 2,3,4,5-tetrahydro-1H-1,3,4-benzotriazepine-5-one derivatives was accomplished in good yields via the intermolecular reductive coupling reaction of 2-nitrobenzoic hydrazides and aldehydes or ketones promoted by the low-valence titanium reagent (TiCl4/Zn system). Structures were established on the basis of elemental analysis, IR and 1H NMR spectra.
