A series of new 1,3,4-oxadiazol-2-yl-acrylic acids was synthesized by cyclization of 4-(2-R-hydrazino)- 4-oxo-2-butenic acids, and their antibacterial and protistocidal activities were studied. The p-substituted benzyl derivatives in the Z-form were shown to exhibit a high protistocidal activity, which exceeded that of the reference drug Baycox (toltrazuril) by several times, whereas the 3-hydroxy-2-naphthyl
4-(2-R-肼基)-4-氧代-2-丁烯酸环化合成了一系列新的1,3,4-恶二唑-2-基-丙烯酸,并研究了它们的抗菌和杀虫活性. Z 型的对位取代苄基衍生物显示出高杀原虫活性,超过参考药物 Baycox (toltrazuril) 的数倍,而 3-羟基-2-萘基衍生物,除了非常高的杀原生生物活性,也表现出中等的抗菌活性。

Zinc complex of (E)-3-[5-(4-methoxyphenyl)-1,3,4-oxadiazol-2-yl]acrylic acid has been prepared; its structure and composition have been elucidated by means of IR and (1)De as well as D-13 NMR spectroscopy. Spectral luminescent properties of the ligand and the complex have been studied. Both compounds exhibit blueviolet luminescence (lambda (max) (fl) 402aEuro'467 nm, phi 0.06-0.82) with low self-absorbance of the emitted light.

Two procedures have been proposed for the synthesis of pure (E)- and (Z)-3-(5-aryl-1,3,4-oxadiazol-2-yl)acrylic acids, by one-step cyclization of (Z)-4-(2-aroylhydrazinyl)-4-oxobut-2-enoic acids or via initial cyclization of (Z)-4-(2-aroylhydrazinyl)-4-oxobut-2-enoic acids to 5-(aroylhydrazinylidene)furan-2(5H)-ones which are then converted into the target compounds.
