Abstract A series of 2,2′-(dihydropyrimidine-1,3(2H,4H)-diyldimethanediyl)bis(substituted-phenols) was synthesized using a Mannich-type reaction between the macrocyclic aminal 1,3,7,9,13,15,19,21-octaazapentacyclo[19.3.1.13,7.19,13.115,19]octacosane (OAPO) (1) and substituted phenols in basic media. These previously unreported compounds were separated from the reaction mixture by column chromatography
摘要 利用大环胺缩醛 1,3,7,9,13 之间的 Mannich 型反应合成了一系列 2,2'-(dihydropyrimidine-1,3(2H,4H)-diyldimethyldiyl)bis(已取代苯酚)。 ,15,19,21-octaazapentacyclo[19.3.1.13,7.19,13.115,19]octacosane (OAPO) (1) 和碱性介质中的取代酚。这些以前未报道的化合物通过柱色谱以高纯度形式从反应混合物中分离出来,产率为 25-75%。使用 AM1 型半经验量子化学计算预测了最稳定的构象异构体。图形概要
