Abstract: Three new asymmetric Schiff base compounds, (E)-methyl 2-(2-(2-hydroxy-3-methoxybenzylideneamino)ethylamino)cyclopent-1-enecarbodithioate[H 2 cd3-OMesalen](1), (E)-methyl 2-(2-(3,5-di-tert-butyl-2-hydroxybenzylideneamino)ethylamino)cyclopent-1-enecarbodithioate[H 2 cd di tertbutsalen] (2) and (E)-methyl2-(2-(3-hydroxy-4-methoxybenzylideneamino)ethylamino)cyclopent-1-enecarbodithioate[H 2 cd4-OMesalen] (3) have been prepared. The compounds have been studied with IR, 1 H NMR, 13 C NMR and microanalysis. The crystal structure of (1) has been also determined.
