intramolecular palladium(II)-catalyzed regioselective 6-endo-trig or 6-exo-trig annulation through direct C–H activation is presented as a method for the diversity-oriented synthesis of highly substituted quinolinones from pyridones. The reaction occurs under mild conditions and exhibits excellent regioselectivity, good functional group tolerance, and broad applications. This innovative approach has been
在此,提出了一种通过直接 C-H 活化的新型分子内钯 (II) 催化区域选择性 6- endo-trig或 6- exo-trig成环,作为从吡啶酮以多样性为导向合成高度取代的喹啉酮的方法。该反应在温和的条件下发生,具有优异的区域选择性、良好的官能团耐受性和广泛的应用。这一创新方法已成功用于合成 Glycopentanolone A 和 ( R )-(+)-Tipifarnib 中间体。
