Heteroatom-Guided, Palladium-Catalyzed Regioselective C–H Functionalization in the Synthesis of 3-Arylquinolines
摘要:
A new approach for the regioselective functionalization of the C-3-position of quinolines is described. The method utilizes heteroatom guided regioselective C-3 palladation followed by arylation via transmetalation with aryl boronic acids to yield 3-aryl-N-acyl-1,2-dihydroquinolines. In a one-pot sequence, N-deacylation followed by aromatization leads to important 3-arylquinolines in good yields.
The invention relates to new quinoline derivative compounds of formula (I), to pharmaceutical compositions comprising said compounds, to processes for the preparation of said compounds and to the use of said compounds in the treatment of diseases, e.g. cancer.
3-Aryl quinolines are readily synthesized by a novel Friedlander-type reaction with 3-oxo-2,3-diaryl-propionaldehydes and 2-amino arylaldehydes. A preliminary mechanism of this novel one pot, two-step synthesis has been explored with the proofs of isolation of the enaminone intermediate and the eliminated benzoic acid in this reaction.
