Abstract
Abstract. The synthesis of 5-7 membered oxygenated heterocycles by intramolecular aminooxygenation of unsaturated alkenes using commercially available N-fluorobenzenesulfonimide an amination reagent and the TpiPr2Cu(NCCH3) as precatalyst is reported. With unsaturated aliphatic carboxylic acids, the corresponding lactones are obtained from moderate to almost quantitative yields employing a catalyst loading of 2.5 mol% under mild conditions, whereas 2-vinylbenzoic acids originate low-er yields.
期刊介绍:
Advanced Synthesis & Catalysis (ASC) is the leading primary journal in organic, organometallic, and applied chemistry.
The high impact of ASC can be attributed to the unique focus of the journal, which publishes exciting new results from academic and industrial labs on efficient, practical, and environmentally friendly organic synthesis. While homogeneous, heterogeneous, organic, and enzyme catalysis are key technologies to achieve green synthesis, significant contributions to the same goal by synthesis design, reaction techniques, flow chemistry, and continuous processing, multiphase catalysis, green solvents, catalyst immobilization, and recycling, separation science, and process development are also featured in ASC. The Aims and Scope can be found in the Notice to Authors or on the first page of the table of contents in every issue.
