Abstract Heating of 2-deoxy- D - arabino -hexonic acid results in substantial lactonization on melting. Decomposition of the lactone involves dehydration, decarboxylation, and fission to provide mainly water, 5-(2-hydroxycthylidene)-2( 5H )-furanone, carbondioxide, carbon monoxide, acrylaldehyde, and acetic acid. 3-Deoxy- D - ribo -hexono-1,4-lactone, which could not readily undergo β-elimination, is thermally more stable and gives a mixture of fission and dehydration products.

2-脱氧-D-阿拉伯-己酸和3-脱氧-D-核糖-己内酯-1,4-内酯的热降解

摘要对2-脱氧-D-阿拉伯糖基己酸进行加热导致熔融时发生大量内酯化。内酯的分解涉及脱水，脱羧和裂变以主要提供水，5-（2-羟基亚乙叉基）-2（5H）-呋喃酮，二氧化碳，一氧化碳，丙烯醛和乙酸。3-脱氧-D-核糖-己烯-1,4-内酯不易进行β-消除，在热方面更稳定，并提供裂变和脱水产物的混合物。
