A variety of substituted 2-arylethynesulfonamides were prepared by a two-step sequence: 1. preparation of 2-oxo-2-arylethanesulfonamides by reaction of the appropriate methanesulfonamide carbanion with a substituted benzoic ester, 2. dehydration of the resulting ketone by 2-chloro-N-methylpyridinium iodide / NEt3.
通过两步操作制备了各种取代的2-芳基乙炔磺酰胺:1.通过适当的甲磺酰胺碳负离子与取代的苯甲酸酯反应制备2-氧代-2-芳基乙磺酰胺,2.通过2-脱水生成的酮氯-N-甲基吡啶碘化物/ NEt 3。
