  摘要：

  AbstractA novel ruthenium‐catalyzed oxidative alkenylation/annulation cascade reaction is described for synthesizing 3‐methyleneisoindolin‐1‐ones. In the protocol, the NH imidate is applied efficiently as a directing group in ruthenium‐catalyzed CH activation, generating various 3‐methyleneisoindolin‐1‐ones with high regio‐ and stereoselectivity in moderate to good yields.magnified image

  Highly stereoselective intermolecular reactions of electron-deficient alkynes with N-hydroxyphthalimides for efficient construction of N-unprotected 3-methyleneisoindolin-1-ones have been developed through base catalytic strategies. The reaction of alkynoates with N-hydroxyphthalimides catalyzed by Bu3P in DMF at 150 degrees C gave the corresponding 3-methyleneisoindolin-1-ones with a (Z)-configuration, while the reaction of alkynoates with N-hydroxyphthalimides catalyzed by K2CO3 in DMF at 60 degrees C gave the corresponding 3-methyleneisoindolin-1-ones with an (E)-configuration, and (Z)-3-methyleneisoindolin-1-ones were obtained when alkyne ketones reacted with N-hydroxyphthalimide.
