参考标题:Selective N,N-Functionalisation Of Cyclam: Crystal Structure Of The Cu2+ Complex Of 1,4,8,11-Tetra-Azacyclotetradecane-1,8-Diacetic Acid And The Tricyclic Lactam 15,18-Dioxo-1,5,8,12-Tetra-Azatricyclo[10.2.2.25.8]Tetradecane 作者:Ian M. Helps,David Parker,James Chapman,George Ferguson 摘要:A General Synthetic Method For The Synthesis Of 1,8-Disubstituted Derivatives Of The 14-Membered Tetra-Aza Macrocycle, 'Cyclam', Involves Selective Ditosylation: In The Cu2+ Complex Of The 1,8-Diacetic Acid Derivative, The Copper Is Six-Co-Ordinate With Elongated Cu-O Interactions And This Macrocycle Undergoes Lactamisation To Form A Paracyclophane-Like Tricyclic Lactam Which Is Resistant To Acidic
