1,3-Acylrearrangements by Cyclisation of Thioureas with Imidochlorides of Oxalic Acid - An Approach to interesting Thiocarbonylic Systems

By cycloacylation of various substituted thioureas with bis-imidochlorides of oxalic acid the new thiazolidines 3, 4 and isomeric imidazolidines 5, 6 are obtained.Especially when triethylamine is used as a base the main products are the deeply coloured 4-

Derivatives of Imidazolidines from Oxalic Amidines

Tetraarylsubstituted oxalic amidines 1 react with acyl chlorides, phosgene, thiophosgene, chlorocarbonylsulfenylchloride, isocyaniddichlorides, and N-aroyl-1-chlorothio-formimidoylchlorides 7 to give the corresponding 5-membered heterocycles 3,4,5 and 8.Isocyanates 9 and isothiocyanates 10 react with oxalic amidines to yield imidazolidines 11, 12 and ureas 13, 14.Hydrolysis of 3-5, 8, 11, 12 leads to the corresponding oxo compounds 15, 16.
