were formed, accompanied by formose sugars. The initial molar amount of HAP corresponded to the sum of the compounds substituted with the phenyl group including benzaldehyde and benzoic acid. The retro-aldol reaction of the HAP derivatives is likely to be involved in the overall reaction to yield glycolaldehyde or trioses, which are good accelerators for formose formation.
将甲醛快速羟醛加成到 2-羟基苯乙酮 (HAP) 中,这是一种有效的甲醛形成促进剂,在 35°C 下,在 40% 的甲醛甲醇混合物中,产生 HAP 与一分子和两分子甲醛的加成产物, HAP 和 Ca(OH)2。在整个反应过程中,没有检测到另外的加成产物有超过两个分子的甲醛附着在 HAP 上。相反,形成了苯甲醛和苯甲酸,伴随着甲糖。HAP 的初始摩尔量对应于被苯基取代的化合物的总和,包括苯甲醛和苯甲酸。HAP 衍生物的逆羟醛反应很可能参与生成乙醇醛或丙糖的整个反应,它们是形成甲糖的良好促进剂。
