oxidative C(sp3 )-H amidation for the synthesis of β -lactams using t BuOO t Bu. This method is based on Kharasch-Sosnovsky amidation and does not require prefunctionalization of C(sp3 )-Hbonds or the installation of a directing group, thereby allowing for the straightforward synthesis of β -lactams. Our intramolecular functionalization protocol can be extended to diverse benzylicC(sp3 )-Hbonds and
β-内酰胺由于在天然产物和药物中普遍存在而成为重要的结构基序。我们在此报告了使用t BuOO t Bu合成β-内酰胺的Cu催化的分子内氧化C(sp 3)-H酰胺化反应。该方法基于Kharasch-Sosnovsky酰胺化,不需要C(sp 3)-H键的预功能化或定向基团的安装,从而可以直接合成β-内酰胺。我们的分子内功能化协议可以扩展到各种苄基C(sp 3)-H键,并显示出色的官能团耐受性。
