Sixteen new and one known unsymmetrical open-chain diacylamines were synthesized by sodium methoxide catalyzed acylation of amides with carboxylic esters and acylamino-carboxylic esters, or acylureas with acylamino- carboxylic esters and α-amino acid esters.
Visible-Light-Driven Oxidation of N -Alkylamides to Imides Using Oxone/H 2 O and Catalytic KBr

Imides are prepared conveniently by visible-light-driven oxidations of various N -alkylamides under mild conditions. The majority of the reactions proceed efficiently by using Oxone as the oxidant in the presence of a catalytic amount of KBr in H 2 O/CH 2 Cl 2 under irradiation by an 8 W white LED at room temperature. Experimental studies suggest that an imine, obtained from the substrate amide via a radical process, is the key intermediate.
Synthesis of 1,3,5-trisubstituted-1,2,4-triazoles by microwave-assisted N-acylation of amide derivatives and the consecutive reaction with hydrazine hydrochlorides
Lee, Jongbok,Hong, Myengchan,Jung, Yoonchul,Cho, Eun Jin,Rhee, Hakjune
, p. 2045 - 2051 (2012/04/10)
Facile and efficient procedures for the N-acylation reaction of amide derivatives with various acid anhydrides and the cyclization reaction of N-acylated amide derivatives with various hydrazine hydrochlorides were described. The reactions were carried out under microwave irradiation to give products in good yields in a few minutes. The synthesis of 1,3,5-trisubstituted- 1,2,4-triazoles from benzamides can also be accomplished in a simple one-pot sequential reaction.
Novel chromium(VI) catalyzed oxidation of N-alkylamides to imides with periodic acid
Xu, Liang,Zhang, Suhong,Trudell, Mark L.
, p. 1668 - 1669 (2007/10/03)
A novel and practical procedure for preparation of imides is described using chromium(VI) oxide to catalyze the oxidation of N-alkylamides with periodic acid in the presence of acetic anhydride in acetonitrile.
