Catalytic Synthesis of Tricyclic Quinoline Derivatives from the Regioselective Hyand C—H Bond Activation Reaction of Benzocyclic Amines and
37- 145 droamination
Alkynes. — Both five- and six-membered benzocyclic amines readily undergo regioselective coupling reaction with terminal alkynes to give the desired cyclized products
(III) and (V) in good to high yields (42-99%). No coupling product is found with sterically demanding terminal alkynes and internal alkynes. — (YI*, C. S.; YUN, S. Y.;
