Synthesis of substituted 1,2,4-oxadiazoles from substituted acid chlorides and amidoximes under mild conditions

Synthesis and antiproliferative efficiency of novel bis(imidazol-1-yl)vinyl-1,2,4-oxadiazoles

A new class of bis(imidazol)vinyl-1,2,4-oxadiazoles were synthesised and their anti-proliferative efficiency was tested against HCT116 and A549 cancer cell lines.

An efficient mEthod for the One-Pot Tandem Synthesis of 3,5-Disubstituted-1,2,4-Oxadiazoles from Benzyl Halides

The first example of a one-pot tandem approach for the synthesis of 3,5-disubstituted-1,2,4-oxadiazole derivatives from benzyl halides and amidoxime is reported. Derivatives of 3,5-disubstituted 1,2,4-oxadiazole were obtained in excellent yields under mild conditions using DMSO in the absence of an additional oxidant. Benzyl bromides bearing a range of substituents proved to be suitable substrates for this method which provides a very efficient and convenient application of the Kornblum oxidation.

Design and synthesis of N¹,N⁵-bis[4-(5-alkyl-1,2,4-oxadiazol-3-yl)phenyl]glutaramides as potential antifungal prodrugs

A facile three step synthesis of a group of N1,N5-bis[4-(5-alkyl-1,2,4-oxadiazol-3-yl)phenyl]glutaramides, N1,N5-bis[4-(1,2,4-oxadiazol-3-yl)phenyl]glutaramide and N1,N5-bis[4-(5-oxo-4,5-dihydro-1,2,4-oxadiazol-3-yl)phenyl]glutaramide is described. These products are designed to function as masked bis-amidine prodrugs of a promising N1,N5-bis[4-(N'-(carbamimidoyl)phenyl]glutaramide antifungal lead.
