Abstract
Cyclization of alkyl 2-methyl-5-acetylfuran-3-carboxylate carbethoxyhydrazone according to Hurd-Mori reaction afforded alkyl 2-methyl-5-(1,2,3-thiadiazol-4-yl)-3-carboxylate. Its bromination with N-bromosuccinimide yielded 2-bromomethyl derivative. The latter was involved in the Delepine reaction to form alkyl 2-aminomethyl-5-(1,2,3-thiadiazol-4-yl)-3-carboxylate. Acylation of the product synthesized with chloroacetyl chloride and subsequent treatment with morpholine or 4-methylpiperidine gave the corresponding pseudopeptides. In the course of these transformations the furylthiadiazole fragment retained its stability.
