Gold(III)-catalyzed regioselective synthesis of vinyl-substituted pyrazolo[1,4]-oxazepines via 7-exo-trig cyclization
Vinyl-substituted pyrazo[1,4]-oxazepines were prepared through an intramolecular regioselective cyclization method under gold catalysis. This organic transformation achieved selective C–N bond formation via 7-exo-trig cyclization, resulting in vinyl-containg pyrazolo[1,4]-benzooxazepines and pyrazolo[1,4]-naphthoxazepines in one-pot with moderate to very good yields.
期刊介绍：
Tetrahedron publishes full accounts of research having outstanding significance in the broad field of organic chemistry and its related disciplines, such as organic materials and bio-organic chemistry.
Regular papers in Tetrahedron are expected to represent detailed accounts of an original study having substantially greater scope and details than that found in a communication, as published in Tetrahedron Letters.
Tetrahedron also publishes thematic collections of papers as special issues and ''Reports'', commissioned in-depth reviews providing a comprehensive overview of a research area.
