Abstract
2-Oxo-1,3-imidazolidinebis(carbothioamide)s and 2,4-dioxo-1-imidazolidinecarbothioamides were prepared by the reaction of dimethyl 2-oxo-1,3-imidazolidinebis(carbodithioate) (1b) and methyl 2,4-dioxo-1-imidazolidinecarbodithioate (2b) with amines, respectively. The reaction of 2-oxazolidone with carbon disulfide gave 2-oxo-3-oxazolidinecarbodithioic acid, the methyl ester of which (4b) led to 2-oxo-3-oxazolidinecarbothioamides. Esters 1b, 2b, and 4b reacted with hydrazine hydrate to give the corresponding thiohydrazides, from which thiosemicarbazone derivatives were obtained. Macrocyclic thioureas were synthesized by the reaction of 1b with aliphatic diamines, polyether-containing diamines, and polyamines.
