  General Approach to Nitrogen-Bridged Bicyclic Frameworks by Rh-Catalyzed Formal Carbenoid Insertion into an Amide C–N Bond

  摘要：

  Various nitrogen-bridged bicyclic skeletons are found in bioactive natural products and pharmaceuticals. The development of a new reaction to construct these molecular frameworks has attracted considerable attention in synthetic organic chemistry. We developed a novel synthetic method for obtaining a wide variety of nitrogen-bridged bicyclic compounds with a catalytic process, Rh-catalyzed formal carbenoid insertion into an amide C-N bond. Using 0.1-0.4 mol % Rh-2((NHCOBu)-Bu-t)(4) catalyst, various azabicydo[X.Y.Z]alkane derivatives were obtained in good to excellent yield, successfully demonstrating the broad substrate scope of the developed process. Experimental and computational studies to elucidate the reaction mechanism revealed that the formal insertion reaction of a carbenoid into an amide C-N bond proceeded via the formation of Rh-associated N-ylides, followed by an acyl group-selective Stevens [1,2]-shift through a concerted addition/elimination process on the sp(2)-hybridized carbon.

  DOI：10.1039/d0nj01209b

  日期：——

  Access to the γ-amino-β,γ-unsaturated acyl scaffold was established by applying xanthate chemistry to enamides. This original β-C(sp2)–H alkylation is regioselective and exhibits broad substrate scope and good functional group tolerance. The large availability of xanthates is advantageous to the scope of the reaction which combines a radical process and a polar reaction.
