An expeditious, practical, and mild method for the reduction of amides to amines is reported. The procedure is based on the activation of amides with titanium tetrachloride followed by reduction with lithium aluminum hydride. The reducing system can be applied to the reduction of tertiary and secondary amides giving the corresponding amines in good yields. The protocol was also extended to the reduction...
A mild method for the aminolysis of carboxylic acid chlorides to give amides is disclosed. Reactions are carried out in the presence of silver acetate in non-aqueous environments under heterogeneous phase conditions. Amides are easily recovered in very good to excellent yields and without racemization. The approach is successful in forming peptide bonds starting from N-(4-nitrobenzenesulfonyl)-amino...
