An efficient method has been developed for the synthesis of 7′-arylspiroadamantane-[2,3′]-(1′,2′,4′,5′,7′-tetraoxazocanes)} by the ring transformation reaction of spiroadamantane-[2,3’]-(1′,2′,4′,5′,7′-pentaoxacane)} with arylamines in the presence of Sm(NO3)3·6H2O as the catalyst. NMR signals of the synthesized compounds were assigned considering the conformation dynamics of the tetraoxazocane ring
通过螺环的环转化反应,已开发出一种有效的方法来合成7'-芳基螺adamantane- [2,3']-(1',2',4',5',7'-四恶唑烷)}在Sm(NO 3)3 ·6H 2存在下,用芳基胺adamantane- [2,3']-(1',2',4',5',7'-五氧六环)}}以O为催化剂。考虑到具有两个刚性过氧化物键的四恶唑烷环的构象动力学,对合成化合物的NMR信号进行了分配。通过X射线衍射研究了某些化合物的结构。用DSC法测定单晶的热稳定性。化合物7'-(2-甲基苯基)螺金刚烷-[2,3']-(1',2',4',5',7'-四恶唑烷)}和7'-(4-氟苯基)螺金刚烷-[2,3']-(1',2',4',5',7'-四恶唑烷)}对癌细胞具有细胞毒性。
