  Dynamic kinetic asymmetric transfer hydrogenation of racemic 2,4-diaryl-2,3-dihydrobenzo[b][1,4]diazepines catalyzed by chiral phosphoric acids

  摘要：

  Dynamic kinetic Transfer hydrogenation reaction of 2-methyl-2,4-diaryl-2,3-dihydrobenzo[b][1,4]diazepines, using phosphoric acids as catalysts and Hantzsch ester as hydride source, has been studied. A 3,3'-H8-binol derived phosphoric acid has been identified the optimal chiral catalyst for this transformation, affording 1,3-diamine derivatives with up to 8/1 dr, 86% ee and 94% ee for the major and minor diastereomers, respectively.

  The title hydrogenation reaction is achieved in the presence of phosphine‐free, chiral, cationic ruthenium–diamine complexes and provides facile access to various chiral seven‐membered N‐containing heterocycles. A reversal of enantioselectivity is observed simply by changing the achiral counteranion of the catalyst.
