procedures for the catalytichydrosilylation of secondary and tertiary amides under mild conditions have been developed. In the presence of inexpensive zinc catalysts, tertiary amides are easily reduced by applying monosilanes. Key to success for the reduction of the secondary amides is the use of zinc triflate and disilanes with dual SiH moieties. The presented hydrosilylations proceed with excellent
In situ-generated cationic copper/pybox catalyst systems allow for the selective reduction of secondaryamides into the corresponding amines under mild conditions. This novel protocol has a wide substrate scope and shows good functional group tolerance.
This article describes a selective reduction of functionalizedamides, including N‐acyl amino esters and dipeptides, to the corresponding amines using simple [Rh(acac)(cod)]. The catalyst shows excellent chemoselectivity in the presence of different sensitive functional moieties.
