Reduction of amides to imines

Related


Recent Literature


A chemoselective activation of a secondary amide with triflic anhydride in the presence of 2-fluoropyridine enables a mild reduction using triethylsilane, a cheap and rather inert reagent. Imines can be isolated after a basic workup or readily transformed to the aldehydes following an acidic workup. The amine moiety can be accessed by addition of Hantzsch ester to the reaction mixture.

A transition-metal-free catalytic hydrosilylation based on t-BuOK (5 mol %) and (MeO)3SiH or (EtO)3SiH allows the reduction of tertiary amides to their corresponding enamines with high selectivity in very  good yields.
