  Catalytic Enantioselective Carbon Insertion into the β-Vinyl C–H Bond of Cyclic Enones

  摘要：

  Chiral oxazaborolidinium ion-catalyzed C-sp(2)-H functionalization of enones using diazoacetate has been developed. Various beta-substituted cyclic enones were synthesized in high yield (up to 99%) with high to excellent enantioselectivity (up to 99% ee). The synthetic utility of this reaction was demonstrated by the formal synthesis of (+)-epijuvabione.

  β-기능화 사이클릭 이논의 입체 선택적 합성방법이 개시된다. 옥사자보로리디늄 이온 촉매의 존재하에서 비기능화 사이클릭 이논과 다이아조아세테이트를 반응시켜 β-기능화 사이클릭 이논을 입체 선택적으로 합성한다. 이러한 합성방법에 따르면 단일 스텝으로 β-기능화 사이클릭 이논을 고효율 및 입체 선택적으로 합성할 수 있다.

  这是一篇化学领域的文章，介绍了一种新的β-功能化环状亚硝基酮的立体选择性合成方法。在存在八面体氧化铕离子催化剂的情况下，将非功能化环状亚硝基酮和二氮基乙酸酯反应，可以立体选择性地合成β-功能化环状亚硝基酮。根据这种合成方法，可以高效且立体选择性地在单一步骤中合成β-功能化环状亚硝基酮。
