convenient and robust method for the preparation of new CF3-containing 2-quinolones has been developed via a Rh(III)-catalyzed C–H activation/Lossen rearrangement/annulation cascade of N-pivaloyloxy-arylamides with internal alkynes bearing an α-CF3-α-amino acid moiety on the triple bond. This work expands the scope of valuable products that are available through C–H activation/annulation reactions of
