  Synthesis of Lipophilic Paramagnetic Contrast Agents

  摘要：

  The facile, high-yielding synthesis of a series of macrocycles 7a-k in 75-100% yield is reported. The transformation of these compounds to their carboxymethylated analogues 8a-k in 75-90% yield and subsequent gadolinium complexes 9a-k provides a series of homologous neutral paramagnetic contrast agents (PCAs) with tunable lipophilicity. Alkylated cationic intermediates 6a-k are prepared in yields of 72-94% from glyoxal adduct of cyclen (5) and slight excesses of alkyl iodides. The methodology is selective for monoalkylation and amenable to large-scale synthesis.
