of nitrogen-containing iodinated or in some cases brominated heterocycles were converted to the corresponding zincated heterocyclic derivatives by the direct insertion of zinc dust under mild conditions (25 °C to 70 °C, 1–3 h) in a solvent like THF or DMAC. This reaction was extended to the preparation of zincated nucleic acid bases and nucleosides. The reaction of these new zinc reagents toward various
通过在温和条件下(25°C至70°C,1-3小时)将锌粉直接插入溶剂中,将一系列含氮的碘化或某些情况下的溴化杂环转化为相应的锌化杂环衍生物或DMAC。该反应扩展到锌酸化核酸碱基和核苷的制备。这些新的锌试剂通过钯(0)或铜(I)催化各种亲电子试剂的反应,可以制备各种多官能的含氮杂环。
