we describe the dual C(sp3)–H bond functionalization of a tertiary amine through hydride-transfer-induced dehydrogenation, followed by cycloaddition, using an easily preparable diazoester as a new type hydride-acceptor precursor under mild, redox-neutral conditions. With carbene as a hydrogen acceptor, this method was demonstrated by the preparation of a broad range of functionalized isoxazoldines in
在此,我们描述了叔胺的双 C(sp 3 )-H 键功能化,通过氢化物转移诱导的脱氢,然后是环加成,使用易于制备的重氮酯作为新型氢化物受体前体,在温和的氧化还原中性下条件。以卡宾为氢受体,该方法通过以中等至高产率制备多种官能化异恶唑烷来证明。
