Abstract: The title compound, C₂₄H₃₄N₂O₄S₅, is the ditosylated precursor to the mixed aza-thia macrocycle 1,4,7-trithia-10,13-diazacyclopentadecane ([15]aneN₂S₃) and is prepared by reacting bis(2-mercaptoethyl) sulfide with O,O',N,N'-tetratosyl-N,N'-bis(2-oxyethyl)ethylendiamine in dimethylformamide in the presence of Cs₂CO₃. Molecules lie across crystallographic twofold axes. The macrocyclic framework adopts a [33333] conformation and the two tolylsulfonyl groups are directed away from the ring cavity. There is extensive disorder of the methylene groups of the macrocyclic backbone.
