✦ Synopsis

A novel seven-membered ring was unexpectedly isolated from the coupling of dithiodiglycolic acid with 2.2 equiv. of N-hydroxysuccinimide, followed by addition of 0.25 equiv. of methyl (4-aminomethyl)benzoate hydrochloride (2) in the presence of 2 equiv. of triethylamine.

The title compound, C 10 H 14 N 4 O 3 S, is the first example of the fused tricyclic octahydro-1-thia-2,3a,8a-triazacyclopenta[a]indene ring system. The S-containing heterocycle adopts a typical envelope conformation, fused at the 2,3-positions to a 2,3a,4,5,6,7-hexahydroindazol-3-one unit.
