enantioselective synthesis of chiral fluorinated propargylamines was developed through phosphoric acid and ruthenium-catalyzed chemoselective biomimetic hydrogenation of the carbon–nitrogen double bond of fluorinated alkynyl ketimines in the presence of a carbon–carbon triple bond. This reaction features high chemoselectivity and slow background reaction. In addition, selective transformations of the chiral fluorinated
A series of highly substituted 2-perfluoroalkyl-3-iodoquinolines are prepared by two different methods in good to excellent yields under mild reaction conditions. The first method involves iodocyclization of perfluoroalkyl propargyl imines with I2-CAN. The second method involves iodocyclization of perfluoroalkyl propargyl amines using I2 and ICl. The perfluoroalkyl propargyl amines are prepared in
