Conditions for the regioselective substitution for a nitro group in the ortho-position in 2,4,6-trinitrobenzonitrile under the action of thiols (PhCH2SH, HSCH2CO2Et or PhSH) in the presence of K2CO3 or KOH were found, and the intramolecular cyclization of the ortho-fragments -SX and -CN (X = Cl or CH2CO2Et) was performed to afford 3-chloro-4,6-dinitrobenzo[d]isothiazole and 3-amino-2-ethoxycarbonyl-4,6-dinitrobenzo[b]thiophene, respectively.
One of the oldest and most widely used commercial enzyme inhibitors is aspirin, which selectively inhibits one of the enzymes involved in the synthesis of molecules that trigger inflammation.
