An efficient method for the synthesis of 2,5-disubstituted 1,3,4-oxadiazoles and 1,3,4-thiadiazoles has been developed. Various hydrazides or thionyl hydrazides readily react with DMA derivatives in the presence of TiCl4 as a catalyst to afford the desired products. This protocol provides a simple and economical procedure that affords the target products with good yields and wide substrate scope.

The acylation of 5-substituted tetrazoles with carboxylic acid chlorides and anhydrides gives rise to 2,5-disubstituted 1,3,4-oxadiazoles in high yields.The reaction goes without the addition of organic bases at 100-105 deg C.The acylation of 5-substituted tetrazoles in a two-phase organic solvent-water system in presence of tetrabutylammonium bromide yields N-acyltetrazoles, which are converted into 2,5-disubstituted 1,3,4-oxadiazoles on thermolysis.
