Abstract
The site-selective alkylation of α-aminotropones is effectively realized via gold(I)-catalyzed electrophilic activation of allenamides and allenyl ethers, yielding up to 85% in 30 examples. A dedicated and combined spectroscopic and computational investigation accounts for both chemo- and regioselective profiles of the protocol. New opportunities in the chemical space of tropone/tropolone derivatives are identified.
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.
