A mild rhodium-catalyzed annulation of Boc-protected benzamides with diazo compounds via C-C/C-O bond formation has been explored. In the presence of [Cp*RhCl₂]₂, AgSbF₆ and Cs₂CO₃, Boc-protected benzamides can be effectively annulated to yield isocoumarins in 0.5⁻2 h.
已经研究了通过CC / CO键形成温和的铑催化的Boc保护的苯甲酰胺与重氮化合物的环合。在[Cp * RhCl 2] 2,AgSbF 3和Cs 2 CO 3的存在下,Boc保护的苯甲酰胺可以在0.5×2小时内有效地环化生成异香豆素。
