Tuning the reactivity of arylpalladium intermediates enables control of catalytic arylative 5-exo and 6-endo cyclizations of alkynols. The two modes of cyclizations represent a rare example of controllable, regioselective difunctionalization of alkynes. The cyclizations are useful in offering a divergent synthesis of oxygen-containing heterocycles, which is of synthetic use for further derivatization
调节芳基钯中间体的反应性可以控制炔醇的催化芳基化 5-exo 和 6-endo 环化。这两种环化模式代表了炔烃可控、区域选择性双官能化的罕见例子。环化可用于提供含氧杂环的发散合成,其对于进一步衍生化具有合成用途。hNK-1 受体拮抗剂的正式合成也展示了我们芳基化环化的效用。
