The E and Z isomers of 3-(benzoxazol-2-yl)prop-2-enoic acid

An investigation to show that the carboxylic acid group and the double bonds were coplanar in (E)-3(benzoxazol-2-yl)prop-2-enoic acid. A strong hydrogen bond with the carboxylic group as donar and the pyridine like N atom as an acceptor contributed to the observed supramolecular structure. A one-pot synthesis was carried out by mixing equimolar quantities of maleic anhydride and o-aminophenol in tetrahydrofuran (THF). It was observed that by using Ac 2O as catalyst at a temperature of 323 K, the isomer(I-Z) and isomer(I-E) were obtained.
