The reaction of bis(1,3,4-thiadiazolo)-1,3,5-triazinium (or ”5/6/5î) halides 1 with 1,4,8,11-tetraazacyclotetradecane (2) and tris(2-aminoethyl)-amine (6) yields new N-functionalized cyclams (3a-d) as well as the complex tertiary amine 7. All of the NH or NH2 groups in 2 and 6 are transformed into (chiral) guanidyl moieties. The structure of a representative of 3 was confirmed by single crystal X-ray analysis.
双(1,3,4-噻二唑)-1,3,5-三嗪(或 "5/6/5î)卤化物 1 与 1,4,8,11-四氮杂环十四烷 (2) 和三(2-氨基乙基)-胺 (6) 反应,生成新的 N-官能化环烷 (3a-d) 以及复合叔胺 7。2 和 6 中的所有 NH 或 NH2 基团都转化为(手性)鸟苷基。单晶 X 射线分析证实了具有代表性的 3 的结构。
