Synthesis of New Derivatives of 2-Imino-2,5-dihydrofurans Containing 4-Oxothiazolidine Ring

Abstract The reactions of 5,5-dialkyl-N-alkyl-2-imino-2,5-dihydrofuran-3-carboxamide thiosemicarbazones with diethyl acetylenedicarboxylate and maleic anhydride in absolute ethanol gave rise to potentially bioactive compounds containing iminodihydrofuran and 4-oxothiazolidine rings. The synthesized compounds were characterized by 1H and 13C NMR spectroscopy and elemental analysis data.
