  Organocatalytic Asymmetric C–H Vinylation and Arylation of N-Acyl Tetrahydroisoquinolines

  摘要：

  The first organocatalytic enantioselective oxidative C-H functionalization of N-acyl tetrahydroisoquinolines with vinyl and aryl boronates promoted by a chiral Bronsted acid is described. This metal-free process tolerates a wide range of electronically varied N-acyl tetrahydroisoquinolines and structurally diverse boronates with good to excellent enantioselectivities.

  Reissert-like alkenylation of azaaromatic compounds by the use of alkenylzirconocene chloride as a nucleophile was carried out in the presence of a stoichiometric amount of ClCO2Et. The regioselectivity of the nucleophilic attack depends on reacting heterocycles, solvent, and the presence of copper catalyst. Thus, the reaction of quinoline derivatives with alkenylzirconocene chloride in MeNO2 proceeded in a preferential 1,2-addition manner to give N-ethoxycarbonyl-2-alkenyl-1,2-dihydroquinolines, and the reaction of pyridine in CH2Cl2 under Cu(I)-catalyzed conditions proceeded in a 1,4-addition manner to give N-ethoxycarbonyl-4-alkenyl-1,4-dihydropyridine. The alkenylation of 3,4-dihydroisoquinoline with alkenylzirconocene chloride was also carried out in an enantioselective manner under Cu(I)/chiral Box-catalyzed conditions to give alkenylated tetrahydroisoquinoline compound (75%ee).
