Abstract A simple and efficient, one-pot approach for the synthesis of ether-linked diisoxazole derivatives has been developed through sequential reactions, which includes O-propargylation of 2-bromohomoallylic alcohols with propargyl bromide in the presence of sodium hydride in THF, and 1,3-dipolar cycloaddition by the addition of hydroximinoyl chlorides and triethylamine. This protocol provides some
