Abstract
A series of(E)-1,2-bis(1,3,4-oxadiazol-2-yl)ethenes with a variety of aroma tic substituents in the 5-positions of the heterocycles was prepared by acy lation of the corresponding tetrazoles with fumaryl chloride and subsequent thermal ring transformation. The modified Huisgen reaction renders a new p athway to 3-(1,3,4-oxadiazol-2-yl)propenoic acids and subsequently to the t itle compounds with different substituents.
