  sterically hindered alcohols has been successfully developed via radical–radical coupling reactions enabled by mild and redox-neutral photocatalysis. With alkylsilicates as the radical precursors, a range of primary alkyl radicals bearing various functional groups could couple with a range of phthalimides and activated ketones.

• Regioselective Pd-Catalyzed Aerobic Aza-Wacker Cyclization for Preparation of Isoindolinones and Isoquinolin-1(2<i>H</i>)-ones

  日期：2012.1.6

  A switchable regioselective intramolecular aerobic aza-Wacker cyclization catalyzed by palladium is presented. Isolndollnones or isoquinolin1(2H)-ones could be prepared selectively from the same substrates using different catalysts. The type and steric hindrance of the ligands may be the variables most significant for regiocontrol.
• Rhodium-Catalyzed Cyclocarbonylation of Ketimines via C–H Bond Activation

  日期：2016.5.23

  A novel rhodium-catalyzed oxidative cyclocarbonylation of ketimines via cleavage of two C-H bonds was established, which provided a direct and reliable method for the synthesis of a wide range of 3-methyleneisoindolin-1-ones with mostly moderate yields. Preliminary experimental mechanistic studies and DFT calculations revealed that this reaction proceeds via imine-enamine tautomerization, N-H cleavage, C-H bond activation, CO insertion, and reductive elimination. The mechanism studies further ruled out an isolated cyclometalated rhodium complex being involved in the present reaction, which was different from many other documented rhodium-catalyzed C-H cyclization reactions.

  Brønsted acid-catalyzed dehydration of 3-alkyl-3-hydroxyisoindolin-1-ones is discussed. The reaction is efficiently catalyzed by methanesulfonic acid in acetonitrile and provides the corresponding 3-methyleneisoindolin-1-ones. The E/Z stereochemistry around the exocyclic double bond is in strong correlation with the size of the N-substituent. Selective formation of only one stereoisomer can be controlled
