N-Unsubstituted cyclic imides were readily synthesized in deep eutectic solvent (DES) choline chloride (ChCl)/urea from anhydrides with urea. Urea serves as both a DES component and a nitrogen source, which endows the protocol with advantages of smooth reaction, easy separation of products, simple recovery and recycling of ChCl/urea.

Page/Page column 28; 29, (2013/03/26)
The invention relates to novel amidoalkylpiperazinyl derivatives of tricyclic heterocyclic systems of general formula (I), wherein Z represents -NH- and X represents -S-, or Z represents -S- and X represents >C=C1 represents H or -CH3, R6 and R7 both represent H, n is an integer from 0 to 4 inclusive, G represents a cyclic amide or imide moiety, and optical isomers, geometric isomers, and pharmaceutically acceptable salts thereof. The compounds may be useful for the treatment and/or prevention of the central nervous system disorders.

Molecular nitrogen was incorporated into amides and imides by the reaction of titanium-nitrogen complex 1 prepared from TiCl3 and Mg under N2 in THF with acyl chlorides 3.The cyclic imides 10, 12, 14 and quinazoline 16 were obtained by the reaction of isocyanate complex 6 generated by fixation of CO2 into titanium complex 1 with the corresponding cyclic anhydrides 9, 11, 13 and benzoxazone 15.
