Crystal Structure of Derivative of H4-NOBIN and the Applications in Hetero-Diels-Alder Reaction

Novel Schiff bases of H4'-NOBIN 5a and 5b were synthesized by condensation of 3 with aldehydes. Compound 5b was structurally characterized by single-crystal X-ray diffraction.The asymmetric hetero-Diels-Alder reactions were carried out with high yields and good enan-tioselectivities in the presence of Ti-(S)-5a complex as catalyst. Crystallographic data for 5b: C27H22BrNO, Mr = 456.37, triclinic, space group P1 with a = 9.1618(2), b = 10.3836(2), c = 12.7718(2) A, α = 105.4860(10),β = 94.6360(10), γ = 108.4610(10)°, V = 1092.32(4) A3, Z = 2, Dc = 1.388 g/cm3, μ = 1.900 mm-1, F(000) = 468, R = 0.0476 and wR = 0.1248 for 3092 observed reflections (I > 2σ(Ⅰ)).
