A straightforward process for the N-alkylation of amines has been developed applying readily available carboxylicacids and silanes as the hydride source. Complementary to known reductive aminations, effective C-N bond construction proceeds under mild conditions and allows obtaining a broad range of alkylated secondary and tertiary amines, including fluoroalkyl-substituted anilines as well as the bioactive
A simple and efficient catalyst-free chemoselective reductive amination of primary amines and aldehydes to synthesis of tertiary and secondaryamines with borane complex was developed. Primary amines are converted into tertiary and secondaryamines in one pot reaction under mild condition with good functional group compatibility and It does not require any catalyst to participate in this reaction.
