The low-temperature Grignard reaction of mixed carboxylic anhydrides derived from acid chlorides and o-anisic acid to the general synthesis of keto esters is demonstrated for compounds 1–6, although, some limitations on substrate and Grignard reagent species are also encountered; attempts in the oxa series 2 are unsuccessful, and reaction with ω-phenylpropyl Grignard species for 1 and 4 shows a drastic
对于化合物1-6,已证明了酰氯和邻茴香酸的混合羧酸酐的低温格氏反应与酮酯的一般合成,尽管在底物和格氏试剂种类上也遇到了一些限制。在氧杂一系列尝试2是不成功的,并与ω苯丙基格利雅物种反应1只4示出了在酮酯为产率的急剧下降米甲氧基类似物。异常行为可能与特定类型的金属配位配合物的另一种类型有关,该配合物包括正确位于基质或试剂中的醚氧原子
