  • Rhodium-Catalyzed Oxidative C-H Activation/Cyclization for the Synthesis of Phosphaisocoumarins and Phosphorous 2-Pyrones
    作者:Youngchul Park、Jungmin Seo、Sangjune Park、Eun Jeong Yoo、Phil Ho Lee
    DOI:10.1002/chem.201302652
    日期:2013.11.25
    Rhodium‐catalyzed cyclization of phosphinic acids and phosphonic monoesters with alkynes has been developed. The oxidative annulation proceeds with complete conversion of phosphinic acid derivatives and allowed the atom‐economic preparation of useful phosphaisocoumarins with high yield and selectivity. The reaction is tolerant of extensive substitution on the phosphinic acid, phosphonic monoester and alkyne, including
    已经开发了炔烃对次膦酸和膦酸单酯进行铑催化的环化反应。氧化环化反应可进行次膦酸衍生物的完全转化,从而可以经济高效地制备有用的磷化异香豆素,并实现了原子经济的制备。该反应耐受在次膦酸,膦酸单酯和炔烃上的广泛取代,包括卤化物,酮和羟基作为取代基。此外,我们发现烯基膦酸单酯通过与炔烃的氧化环化作用继续生成各种磷2-吡喃酮。机理研究表明,CH键金属化是限速步骤。

  • Synthesis of Phosphaisocoumarins through Rhodium-Catalyzed Cyclization Using Alkynes and Arylphosphonic Acid Monoesters
    作者:Jungmin Seo、Youngchul Park、Incheol Jeon、Taekyu Ryu、Sangjune Park、Phil Ho Lee
    DOI:10.1021/ol401407v
    日期:2013.7.5
    A rhodium-catalyzed cyclization using alkynes and arylphosphonic acid monoesters for the synthesis of phosphaisocoumarins is reported. A number of arylphosphonic acid monoesters were selectively cyclized in high yields with functional group tolerance. In addition, unsymmetrical alkynes are applied in high regioselectivity.
