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
