Amadori and Heyns reaction are landmark reactions of carbohydrate chemistry. Synthesis of simple Amadori and Heyns compounds are complicated by various factors and require tedious column chromatographic or ion chromatographic separations. Herein, we report an improved catalytic method based on classical synthetic method of Amadori and Heyns compounds in light of new understanding of a factor governing the reaction. By utilizing the improved catalytic method, we have accomplished several Amadori compounds of d-tagatose and also numerous other Amadori and Heyns compounds.

再次探讨Amadori和Heyns的合成：非催化形式的临界百分比在催化剂之外发挥了作用

Amadori和Heyns反应是碳水化合物化学的标志性反应。各种因素使简单的Amadori和Heyns化合物的合成变得复杂，并且需要繁琐的柱色谱或离子色谱分离。在本文中，我们鉴于对反应控制因素的新认识，报告了一种基于经典合成方法的Amadori和Heyns化合物的改进催化方法。通过利用改进的催化方法，我们完成了几种d-塔格糖的Amadori化合物，以及许多其他的Amadori和Heyns化合物。
