SYNTHESIS, STRUCTURE, AND SPECTRAL PROPERTIES OF SOME BIOXAZOLES

Article abstract of DOI:10.1007/BF00575250

Syntheses of systems containing two oxazole rings <2'-phenyl-,2'-(2-furyl)-, and 2'-(2-thienyl)-2,5'-bioxazoles, and 2,2'-(2,5-furylene)bisoxazole> from aldehydes obtained by formylating 2-phenyl-, 2-(2-furyl)-, and 2-(2-thienyl)oxazole have been developed.Terephthalate and thiophen-2,5-dicarboxylate esters have been used to obtain 2,2'-(1,4-phenylene)- and 2,2'-(2,5-thienylene)bisoxazoles.The PMR, UV, and luminescence spectra of these systems have been examined, and quantum chemical calculations carried out in the PPP approximation.
