Cycloaddition Reaction of N-Homoallylacetohydrazides with O-Benzoylhydroxylamines under Copper Catalysis: Access to Tetrahydropyridazine Skeletons
We present a practical copper-catalyzed strategy for the amination and cyclization of unactivated alkenes. The transformation employs O-benzoylhydroxylamines as alkylamine precursors to initiate a radical cascade process. This protocol enables the construction of a diverse array of tetrahydropyridazine scaffolds by reacting N-homoallylacetohydrazides with O-benzoylhydroxylamines, ultimately affording a total of 25 structurally varied derivatives.
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.
