| 摘 要： | 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.
