RhIII‐catalyzed C−H functionalization reaction yielding isoindolinones from aryl hydroxamates and ortho‐substituted styrenes is reported. The reaction proceeds smoothly under mild conditions at room temperature, and tolerates a range of functional groups. Experimental and computational investigations support that the high regioselectivity observed for these substrates results from the presence of an
据报道,Rh III催化的 CH 官能化反应从芳基异羟肟酸酯和邻位取代的苯乙烯产生异吲哚啉酮。该反应在室温下温和条件下顺利进行,并耐受一系列官能团。实验和计算研究表明,这些底物观察到的高区域选择性是由于苯乙烯中嵌入的邻位取代基的存在造成的。所得的异吲哚啉酮是合成生物活性化合物的重要组成部分。它们可以在一锅两步反应中轻松获得类似天然产物的化合物异吲哚苯并氮杂卓。选定的异吲哚啉酮可抑制 Hedgehog (Hh) 依赖性多能小鼠间充质祖干细胞向成骨细胞的分化。
