Palladium-catalyzed ring-closing reaction via C-N bond metathesis for rapid construction of saturated N-heterocycles

The ring-closing reactions based on chemical bond metathesis enable the efficient construction of a wide variety of cyclic systems which receive broad interest from medicinal and organic communities. However, the analogous reaction with C-N bond metathesis as a strategic fundamental step remains an unanswered challenge. Herein, we report the design of a new fundamental metallic C-N bond metathesis reaction that enables the palladium-catalyzed ring-closing reaction of aminodienes with aminals. The reactions proceed efficiently under mild conditions and exhibit broad substrate generality and functional group compatibility, leading to a wide variety of 5- to 16-membered N-heterocycles bearing diverse frameworks and functional groups.

Ruthenium-catalyzed transformation of 3-benzyl but-1-ynyl ethers into 1,3-dienes and benzaldehyde via transfer hydrogen

TpRuPPh3(CH3CN)2PF6 catalyzed the transformation of various 3-benzyl but-1-ynyl ethers into dienes and benzaldehyde at a catalyst loading of 5 mol %. This process represents an atypical pattern of transfer hydrogenation. This catalytic reaction can be applied to various derivatives of 2-ethynyl tetrahydrofurans and pyrans to cleave their ether rings and gives diene and tethered aldehyde functionalities, respectively.
