摘要
The first catalytic asymmetric pseudo five-component (AB(2)C(2) type) reaction is reported. A spirocyclic chiral phosphoric acid catalyzed one-pot multicomponent reaction of aromatic aldehydes, anilines and β-ketoesters and afforded highly functionalized enantioenriched tetrahydropyridines with high levels of stereocontrol.
