摘要

Acid-controlled,chemodivergent and redox-neutral annulations for the synthesis of isocoumarins and isoquinolinones have been realized via Rh(Ⅲ)-catalyzed C-H activation.Diazo compounds act as a carbene precursor,and coupling occurs in one-pot process,where adipic acid and trimethylacetic acid promote chemodivergent cyclizations.
