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.

Iodine-mediated synthesis of 3-sulfenylimidazo[1,5-a]pyridines via C–H functionalization has been achieved using dithioesters, 2-methylaminopyridines and sulfonyl hydrazides.
