2-, 3-, or 4-Pyridylmethyl radicals can be made to add to nonactivated alkenes to give a variety of otherwise inaccessible pyridine derivatives. Bicyclic structures can be obtained by combining the radical addition with ionic ring-closure steps.
2-、3-或4-
吡啶基
甲基自由基可以通过加成反应添加到非活化烯烃上,形成多种原本难以获得的
吡啶衍生物。通过将自由基加成与离子环合步骤相结合,可以获得双环结构。
