Preparation of secondary and tertiary amides under neutral conditions by photochemical acylation of amines

, p. 1968 - 1970 (2007/10/03)
The smooth and neutral acylation of amines to form amides by photoactivation of N-acyl-5,7-dinitroindolines is described. An improved acylation of nitroindolines allows the convenient preparation of N-acylnitroindolines. This reaction makes possible the recycling of the nitroindoline released during the photoactivation.

1-Acylimidazoles could be highly activated for acylation by the quarternizing with benzyl halides. 1-Acyl-3-benzylimidazolium halides were powerful acylating agents.Alcohols, phenols, and amines were converted to the corresponding esters and amides in excellent yields under mild conditions.Keywords - 1-acyl-3-substituted imidazolium salts; acylating agents; 1-acylimidazoles; 1-acetyl-3-benzylimidazolium bromide; 1-benzoyl-3-benzylimidazolium bromide
