The reaction between the phenolic Mannich bases 1,3-bis[2′-hydroxybenzyl]imidazolidines and the Mannich intermediary macrocyclic aminal 1,3,6,8-tetraazatricyclo[4.4.1.13,8]dodecane (TATD) was studied under solvent-free conditions. It was established that the major product is a heterocalixarene-type Mannich base, and three linear benzylimidazolidine oligomers were identified as minor products. The formation
在溶剂下研究了酚曼尼希碱1,3-双[2'-羟基苄基]咪唑烷与曼尼希中间大环氨基1,3,6,8-四氮杂三环[4.4.1.1 3,8 ]十二烷(TATD)的反应无条件。已经确定主要产物是杂杯芳烃型曼尼希碱,并且鉴定出三种线性苄基咪唑烷低聚物为次要产物。在本信中分析了这些低聚物的形成,并提出了反应机理。
