Title: | Pentanidium Catalyzed Hydroxylation of Oxindoles with Air | Authors: | YANG YUANYONG | Keywords: | PTC, Oxindole, oxidation, air | Issue Date: | 29-Mar-2012 | Citation: | YANG YUANYONG (2012-03-29). Pentanidium Catalyzed Hydroxylation of Oxindoles with Air. ScholarBank@NUS Repository. | Abstract: | Asymmetric hydroxylation of 3-substituted oxindoles under phase-transfer condition was developed. Good yield and excellent enantiomeric excess were achieved. It was demonstrated that this reductant free condition is actually a two-step reaction. The first step is the hydroperoxidation of the 3-substituted oxindoles followed by kinetic resolution of the hydroperoxide to give the final product with excellent enantiomeric excess. | URI: | http://scholarbank.nus.edu.sg/handle/10635/35557 |
