Bridged-Type Selective Intramolecular Nitrone–Alkene Cycloaddition: Computational Chemistry-Inspired Regioselectivity Control
A regioselective intramolecular nitrone–alkene cycloaddition for synthesizing oxazabicyclo ring-fused indoles is reported. Computational studies guided the development of optimal conditions using In(OTf)3 as a Lewis acidic reagent. This method demonstrates a broad substrate scope, forming seven- and eight-membered carbocycles with various substituents, and provides a versatile route to complex nitrogen-containing scaffolds with potential applications in medicinal chemistry and the total synthesis of biologically active compounds.
期刊介绍:
Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
