neutral molecules. Such encapsulation has been applied for the promotion of both two- or three-component hydrazone condensation in water. For two-component reactions, the yields of the resulting monohydrazones are increased from 5–10 to 90–96%. For three-component reactions of hydrazinecarbohydrazide with 11 aromatic aldehydes, in the presence of the organic cages, the bihydrazone products can be produced
通过两个吡啶鎓衍生的三醛和草酰肼的2 + 3 coupling偶合,在水中原位制备了两个有机笼。高度水溶性的笼子可包裹并溶解线性中性分子。这种包囊已被用于促进水中的两组分或三组分的缩合。对于两组分反应,所得单azo的产率从5-10%增加到90-96%。对于肼基肼与11种芳族醛的三组分反应,在有机笼中,联the产品的产率为88–96%。相反,在不促进有机笼的情况下,9个反应没有得到相应的dihydr产物。
