formation of esters of aldonic acids by treatment with an alcohol in the presence of an acid depends on the nature of the reagents and on the solubility of the products. The formation of aldonolactones is often a favored, competing reaction. Fully acetylated or benzoylated aldonic esters are formed without these restrictions. Among the products, liquid esters and certain of their acid chloride and
摘要在酸存在下用醇处理可形成醛糖酸的酯,取决于试剂的性质和产物的溶解度。醛糖内酯的形成通常是有利的竞争反应。在没有这些限制的情况下,形成了完全乙酰化或苯甲酰化的醛糖酸酯。在产物中,液体酯及其某些酰氯和酰胺中间体是可蒸馏的。基于这项研究的结果,描述了一些合成酯和内酯的有效方法。
