The catalytic asym. 1,4-reduction of α-branched 2-vinylazaarenes by a SPINOL-derived borophosphate has been realized. A SPINOL-derived phosphoric acid is used to form a bifunctional phosphoryl boronate catalyst in situ in the presence of pinacolborane. This asym. 1,4-reduction reaction provides a convenient procedure to access chiral alkylated quinolines I (R1 = 4-Cl, 4-CF3, 3-OMe, etc.; R2 = H, 6-CO2Me, 6-NO2, 7-F, etc.) and benzothiazoles II (R3 = 6-Me, 5-Cl, 6-CO2Me, etc.) in high yields (up to 94%) and with good stereoselectivities (up to 98%).
