The use of selectively tert-butoxycarbonyl protected derivatives of 1,9-dithia-5,13-diazacyclohexadecane 1, 1,7-dithia-4,11-diazacyclotetradecane 2, 1,4,8,11-tetraazacyclotetradecane 3 and 2,5-dioxa-8,11,14-triaza-1,6(1,2)-dibenzenacyclopentadecaphane 4 has enabled the efficient synthesis of new linked heteroditopic macrocyclic systems incorporating combinations of N2S2- and N4- or N3O2-donor sites. Incorporation of two types of binding sites in the respective products makes them suitable candidates for the synthesis of a range of mixed-metal, di- and oligo-nuclear metal complexes.
使用经过选择性叔丁氧羰基保护的1,9-二硫-5,13-二氮杂环十六烷1、1,7-二硫-4,11-二氮杂环十四烷2、1,4,8,11-四氮杂环十四烷3以及2,5-二氧-8,11,14-三氮-1,6(1,2)-二苯并环十五烷4的衍生物,实现了包括N2S2-和N4-或N3O2-供体位点组合在内的新型连结异双位点大环体系的合成。这些产物中引入两种不同类型的结合位点,使它们成为合成一系列混合金属、二核和寡核金属配合物的合适候选。
