Abstract
Novel derivatives of 2-imino-2,5-dihydrofuran-3-carboxamides containing a thiourea residue have been synthesized by the reaction of 2-imino-2,5-dihydrofuran-3-carboxamides with thiosemicarbazide in glacial acetic acid. The synthesized N-substituted iminodihydrofurans have been condensed with ethyl chloroacetate to obtain novel derivatives of iminodihydrofurans containing an oxothiazolidinylidene ring. These methods open up new synthetic approaches to previously unknown systems containing iminodihydrofuran, thiourea and oxothiazolidinylidene fragments.
