  日期：——

  An atom economical synthesis of isoquinolinones and analogues via ligand-free Pd-catalysed C–H and N–H double activation has been developed. A series of isoquinolinones were obtained in good to excellent yields. Good regioselectivities were also observed during the activation reactions with unsymmetrical alkynes. A practical one-pot procedure for the preparation of N–H isoquinolinones is also described.

  A practical one-pot procedure for the preparation of N-H isoquinolones has been developed. This 2-step process via C-H activation of N-alkoxyl benzamides and NaH-mediated dealkoxylation reaction has been demonstrated to be a high yielding alternative methodology for the efficient synthesis of a wide range of representative N-H isoquiolones. In addition, the experimental precedent supported mechanism of the dealkoxylation reaction was also proposed. (C) 2013 Elsevier Ltd. All rights reserved.

  日期：2015.2

  The direct synthesis of isoquinolones from benzamides and alkynes through CH activation was developed by using Pd/C as a heterogeneous catalyst without a ligand under mild conditions. A variety of isoquinolones were obtained in good yields with excellent regioselectivities. The Pd/C catalyst could be recycled three times without a significant decrease in the activity (yields as high as 85 %).
