the synthesis of potentially biologically active 4-tosyloxazole derivatives is described via reaction of imidoyl chloride adducts generated in situ from the reaction of isocyanide and acyl chlorides with p-toluenesulfonylmethyl isocyanide (TosMIC). This reaction was carried out in the presence of sodium hydride as a base and in THF to produce 4-tosyloxazoles in excellent yield.
