Two steps in one reaction : The title relay reaction relies on a combination of an achiral Lewis acid and a chiral Brønsted acid (B*‐H in the scheme). This one‐pot method provides access to tetrahydroquinoline derivatives with multiple continuous stereogenic centers in high stereoselectivity (>20:1 d.r., 98 % ee ).
