An efficient and convenient method for one step conversion of trimethylsilylacetylenes into haloacetylenes has been developed. This method is sufficiently mild to apply a variety of substrates having many kinds of functional group. The validity of this method is demonstrated in the synthesis of simple model compound of esperamicin/calicheamicin aglycon.
