Hydrogenolysis of Amide Acetals and Iminium Esters
Kadyrov, Renat
, p. 170 - 172 (2017/12/26)
Amide acetals and iminium esters were hydrogenated into amines under very mild reaction conditions over common hydrogenation catalysts. This finding provides a new strategy for the selective reduction of amides. The synthetic utility of this approach was demonstrated by the selective reduction of amides bearing ester and nitrile groups.

Paragraph 0151; 0152, (2016/10/04)
The present invention relates to a process for the preparation of amines, comprising the following steps: Reaction of a (i) amide acetal of the general formula (I), or (ii) ketene N,O-acetal of the general formula (II), or (iii) ester imide of the general formula (III) with H2 in the presence of a hydrogenation catalyst, where catalyst and amide acetal or ketene N,O-acetal or ester imide are used in a molar ratio of from 1:10 to 1:100 000 and where a hydrogen pressure of from 0.1 bar to 200 bar is established and where a temperature in the range of from 0° C. to 250° C. is established.

The metabolism of the potent antiarrythmic drug amiodarone (AMI; 1) has yet not been fully investigated. Recently, in vitro experiments revealed that in rabbit-liver microsomes, AMI (1) and its main metabolite MDEA (2) were biotransformed to the hydroxyla
