摘要
以四丁基碘化铵(TBAI)为催化剂,过氧叔丁醇(TBHP)作为氧化剂,在温和的反应条件下实现了叔胺氮的邻位碳原子上sp3-C—H键与亚磷酸酯的氧化偶联,反应条件温和,室温、空气下即可进行,适用范围广泛,产率高,后处理方便.为新的C—P键的形成提供了一条简洁高效的反应路径,并且合成了一系列可能具有重要药理和生物活性的α-氨基磷酸酯化合物.
Activation of sp3-C-H bonds and oxidative phosphonation of sp3-C-H bonds adjacent to a nitrogen atom of tertiary amine were catalyzed by tetrabutylammonium iodide (TBAI) with t-butylhydroperoxide (TBHP) as oxidant under mild reaction conditions. The safe, convenient, and environmentally benign process, as well as the broad substrate scope, low catalyst loading, high selectivity, short reaction time, and good yields make the protocol very practical.
