selective, and controlled oxidative functionalization of CHbondsusingmolecularoxygen as an oxidant remains highly desirable and equally challenging in the development of synthetic methodologies. Presented herein is a one‐pot oxygenase cascade reaction wherein a copper(I)‐catalyzed oxygenase reaction transforms the allylic methyl group in 3‐methylidene oxindoles into an aldehyde, which then undergoes

An efficient stereoselective synthesis of various 3-(3-dimethylaminoprop-2-enylidene)oxindoles has been disclosed. The compounds were synthesized via a vinylogous N,N-dimethylaminomethylenation at the gamma-position of 3-[(1-substituted)ethylidene]oxindoles with DMF-DMA. (C) 2014 Elsevier Ltd. All rights reserved.
