Reactive, selective, and tough, the chiral Lewis acid generated from 1 and SnCl4 catalyzes the enantioselective Diels-Alder reactions of various classes of substrates (see scheme). The reactive species preserves its asymmetric induction ability even in the presence of a large excess of SnCl 4. Importantly, this catalyst system is tolerant to a small amount of moisture, oxygen, and Lewis bases.
