Abstract The action of pyruvic acid on glycerol leads principally to two isomeric, bicyclic lactones 1 and 2 ; this reaction is compared with that employing methyl and ethyl esters of pyruvic acid. The action of pyruvaldehyde or 2,3-butanedione on glycerol leads to bicyclic heterocycles having a secondary ( 5 ) or tertiary ( 6 ) hemiacetal group, respectively. These compounds, and likewise the derived
摘要丙酮酸对甘油的作用主要产生两个同分异构的双环内酯1和2。将该反应与使用丙酮酸的甲酯和乙酯进行比较。丙酮醛或2,3-丁二酮对甘油的作用分别导致具有仲(5)或叔(6)半缩醛基团的双环杂环。这些化合物,以及同样衍生的烷氧基,乙酰氧基和氯代类似物,都受到异头作用,其内异构体在热力学上比外异构体更稳定。
