with NBS in toluene was found to conveniently afford the corresponding carboxylic esters, including those bearing a bulky or long-chain substituent, in satisfactory to excellent yields. This approach not only represents a convenient and economic approach to a direct transformation of an alkoxyamide moiety into the carboxylic ester functional group, via oxidative homocoupling and the subsequent thermal
发现在甲苯中用NBS处理N-烷氧基酰胺可以方便地得到相应的羧酸酯,包括带有大体积或长链取代基的那些羧酸酯,令人满意的至优异的产率。该方法不仅代表通过氧化均偶联和随后的热脱氮将烷氧基酰胺部分直接转化为羧酸酯官能团的方便且经济的方法,而且还促进了位阻羧酸酯的合成。
