, p. 1977 - 1982 (2012)
The direct reductive amination of ketones using the Hantzsch ester in the presence of S-benzyl isothiouronium chloride as a recoverable organocatalyst is reported. A wide range of ketones as well as amines were found to give the expected products in moder

The present invention relates to an iridium-based catalyst compound for hydrogenating reducible moieties, especially imines and iminiums, the catalyst compounds being defined by the formula: (Formula (I)) where ring B is a conjugated ring system with one or more substituents. The catalysts of the invention are particularly effective in reductive amination procedures which involve the in situ generation of the imine or iminium under reductive hydrogenative conditions.
Solvent- and catalyst-free direct reductive amination of aldehydes and ketones with Hantzsch ester: Synthesis of secondary and tertiary amines
Nguyen, Quynh Pham Bao,Kim, Taek Hyeon
, p. 4938 - 4943 (2013/07/25)
A facile and rapid method for the parallel synthesis of a series of secondary and tertiary amines by the direct reductive amination of aldehydes and ketones with Hantzsch ester under solvent- and catalyst-free has been developed. The scope and limitation of this method are described.
