Transition-metal-catalyzed reactions involving reductive elimination between dative ligands and covalent ligands

Reductive elimination is a crucial bond-forming elementary reaction in various transition-metal mediated reactions. Apart from the well-developed classic reductive elimination, the non-classic reductive elimination occurring between a covalent ligand and a dative ligand, which has been known for over 50 years, has gradually attracted much attention from the organic community. By avoiding ppi-dpi repulsion between the filled metal d-orbital and the filled ligand p-orbital and forming a cationic-type molecule, non-classic reductive elimination could facilitate many catalytic reactions that were difficult to be realized via classic reductive elimination. In this review, transition-metal catalyzed C-P, C-S, C-N, and C-C bond-forming reactions with non-classic reductive elimination as the key elementary step are summarized.

Intermolecular Regio- and Stereoselective Hetero-[5+2] Cycloaddition of Oxidopyrylium Ylides and Cyclic Imines

We have developed the first intermolecular hetero-[5+2] cycloaddition reaction between oxidopyrylium ylides and cyclic imines with excellent control of regio- and stereoselectivity. Surprisingly, divergent stereochemistry was observed depending on the substitution pattern of the oxidopyrylium ylide. This new reaction provides quick access to highly substituted nitrogen-containing seven-membered rings?azepanes. Notably, a broad range of oxidopyrylium ylides and cyclic imines participate in this novel hetero-[5+2] cycloaddition reaction and the cycloadducts can be readily transformed into the core skeletons of bioactive natural products. DFT calculations revealed that the cycloaddition proceeds through a stepwise pathway and the imine nitrogen atom serves as the nucleophile to initiate the cycloaddition.
