Abstract
Abstract An unprecedented nickel-catalyzed tandem reaction involving alkyne hydrocyanation and sequential Thorpe reaction has been developed. By employing readily available and less toxic Zn(CN)2 as the cyanide source, both selective alkyne hydrocyanation and tandem cyclization are achieved in a substrate-controlled manner. Mechanistic studies and DFT calculations confirm that the alkenyl nitrile serves as a key intermediate, and hydrogen transfer is identified as the rate-determining step in the Thorpe reaction. This work offers a novel strategy for the construction of α-cyano-β-naphthylamine via a cascade reaction mode.
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.
