  Rh(III)-Catalyzed Coupling of N-Chloroimines with α-Diazo-α-phosphonoacetates for the Synthesis of 2H-Isoindoles

  摘要：

  We report herein the first use of N-chloroimines as effective synthons for directed C-H functionalization. Rh(III)-catalyzed coupling of N-chloroimines with α-diazo-α-phosphonoacetates allows for efficient dechlorinative/dephosphonative access to 2H-isoindoles. Further deesterification under Ni(II) catalysis enables the complete elimination of reactivity-assisting groups and full exposure of reactivity of C3 and N2 ring atoms for attaching structurally distinct appendages.

  reacts with toluene-p-diazonium chloride to give the azo derivative formed by electrophilic substitution at the free α position. However, attempted nitrosation of 1-phenylisoindole gave the product (3) of oxidative dimerisation, while the Mannich reaction gave 5,5'-diphenyldibenzopyrromethene. New routes to the latter system are described.
