A series of N,N,N‐substituted 1,4,7‐triazacyclononanes were prepared by adjusting the reaction sequences and conditions of the intermediate 1,4,7‐tribenzyl‐1,4,7‐triazonane‐2,6‐dione reduction with LiAlH4, the removal of benzyl with Pd/C, and alkylation.
通过调节中间体1,4,7-三苄基-1,4,7-三氮杂-2-2,6-二酮的反应顺序和条件,制备了一系列N,N,N-取代的1,4,7-三氮杂环壬烷用LiAlH 4还原,用Pd / C除去苄基,并烷基化。
