rhenium-based radiopharmaceuticals was conveniently synthesized in high yields through direct reductive N-alkylations of amino acids and their analogues with aldehydes, using NaBH(OAc)3 as an efficient reagent. The mono-, di-, tetra- and even mixed alkylated amino acid derivatives were all prepared in one-pot synthesis.
使用 NaBH(OAc)3 作为有效试剂,通过氨基酸及其类似物与醛的直接还原性 N-烷基化,可以方便地以高产率合成一系列用于锝和铼基放射性药物的有效双功能螯合剂。单-、二-、四-甚至混合烷基化氨基酸衍生物都是在一锅法合成中制备的。
