Abstract: Heating ethyl 4,5-dihydro-4-(4-nitrophenyl)-spiro[1,3,4-thiadiazole-5,2'-camphane]-2-carboxylate in methanol provided the unusual rearrangement product (C₉H₁₉)N₂C(SC₆H₄NO₂)(COOC₂H₅) or C₂₀H₂₅N₃O₄S, whose structure was confirmed by an X-ray diffraction study. The structure features a camphor group connected through a hydrazine fragment to a nitrophenylsulfanyl group and an ethoxycarbonyl group.
