Simple approach to the synthesis of 2-(4(2)- (((4,6-dialkyl-5-oxo-2-thioxohexahydroimidazo[4,5-d]imidazol-1(2H)-yl)imino)methyl)phenoxy)acetates or acetamides (new substituted thioglycolurils) based on the reaction of 5,7-dialkyl-3-thioxoperhydroimidazo[4,5-e]-1,2,4-triazine-6-ones with functionally substituted aromatic aldehydes has been developed. Synthesized thioglycolurils with acetate function can undergo further simple transformation to the corresponding acetamides.

Unexpectedly, nitrosation of 5,7‐dialkyl‐3‐thioxoperhydroimidazo[4,5‐e]‐1,2,4‐triazine‐6‐ones(thiones) with sodium nitrite in glacial AcOH led to 3,3′‐bis(5,7‐dialkyl‐1‐nitroso‐6‐oxo(thioxo)‐1,4,4a,5,7,7a‐hexahydroimidazo[4,5‐e]‐1,2,4‐triazinyl)disulfides that decomposed spontaneously into 1,3‐dialkyl‐5‐thioxohexahydroimidazo[4,5‐d]imidazol‐2(1H)‐ones(thiones) in DMSO‐d6 in the presence of water.
