In this study, we present the catalytic conversion of benzylamides featuring an ortho alkynyl moiety into 1-acylisoindole derivatives via a 1,2-acyl shift. Remarkably, this transformation proceeds without the need for transition-metal catalysts; instead, KOtBu alone serves as the catalyst. This method enables the efficient synthesis of isoindoles from easily accessible amides with an atom economy of
在这项研究中,我们提出了通过 1,2-酰基转移将具有邻炔基部分的苯甲酰胺催化转化为 1-酰基异吲哚衍生物。值得注意的是,这种转变无需过渡金属催化剂即可进行。相反,KO t Bu 单独充当催化剂。该方法能够从容易获得的酰胺中高效合成异吲哚,原子经济性为 100%。
