A novel reaction that generates 1,5-disubstituted carbohydrazones via the carbonylation of tosylhydrazones has been developed. For the first time, the inexpensive, readily available, environmentally friendly, and nongaseous potassium carbonate is used as the carbonyl donor for the transformation. The reaction system exhibited tolerance with various functional groups and affords the desired products
已经开发了一种新的反应,该反应通过甲苯磺酰hydr的羰基化反应生成1,5-二取代的碳hydr。廉价的,易于获得的,环境友好的和非气态的碳酸钾首次被用作转化的羰基供体。该反应系统表现出对各种官能团的耐受性,并以良好至优异的产率提供了所需的产物。预期该反应将是合成糖hydr化合物的有力工具。
