摘要：

We have synthesized a new family of enantiomerically enriched BINAM-derived Schiff base Cr(III) complexes and evaluated them as catalysts for Diels-Alder reactions. These complexes effectively catalyze, for the first time, the enantioselective Diels-Alder reactions between 1,2-dihydropyridine and N-acryloyloxazolidinone to afford 2-azabicyclo[2.2.2]octanes in high yields (89-99%) and with moderate to good enantioselectivities (79-85%).
