Aldehydes as CO Releasing Molecules: In Situ and Ex Situ Giese Reactions and Palladium-Catalyzed Aminocarbonylations
We report the adoption of a two-chamber reactor making use of aliphatic aldehydes in the role of CO releasing molecules (CORMs). Upon photocatalytic conditions, an acyl radical (RCO•) was first formed, prone to lose CO. The resulting alkyl radical was employed in the in situ conjugate addition onto a Michael acceptor (in the first chamber), and the released CO was employed in ex situ palladium-catalyzed aminocarbonylations (in the second chamber) to ensure a 100% atom-economical reaction.
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.
