The conformation of side chain –SCH2COOCH3 in title compounds in crystal agrees with the reactivity of these compounds in base catalysed ring closure in solution. In the 2,4-dinitro derivative, the side chain is oriented towards the unsubstituted ortho-position of benzene ring, in the case of the 2-methoxycarbonyl derivative towards this substituent.
