orthogonally protected cyclam and 1,9-dithia-5,13-diazacyclohexadecane macrocycles, in combination with aza-18-crown-6, has enabled the efficient synthesis of a new heterotritopic macrocyclic ligand incorporating N4-, N2S2- and NO5-donor sites. A similar strategy has allowed the incorporation of cyclam and 1,9-dithia-5,13-diazacyclohexadecane into a cofacial ligand. Further, the synthesis of novel tetramacrocyclic
与zaza-18-crown-6结合使用正交保护的cyclam和1,9-dithia-5,13-diazacyclohexadecane大环化合物可以有效合成新的掺入N 4-,N 2 S的杂三环大环配体2-和NO 5-供体位点。一种类似的策略已允许将cyclam和1,9-二硫杂-5,13-二氮杂环十六烷结合到界面配体中。此外,已经实现了新的四大环配体的合成,其中大环以环状排列连接。各个产物中不同结合位点的可用性使得后者成为合成一系列混合金属多核络合物的合适候选者。
