The Catellani And Retro-Diels-Alder Strategy Was Used In This Domino Process. O-Iodoaniline, With Electron-Donating And Sterically Hindered Protecting Groups, Made The Reaction Selective Toward O-C-H Amination. On The Basis Of Density Functional Theory Calculations, The Intramolecular Buchwald Coupling Of This Reaction Underwent A Dearomatization And A 1,3-Palladium Migration
