Abstract: A three-component cascade boronation-dearomatization reaction of alkenes, a diboron compound, and a pyridinium salt is diclosed, affording chiral boron-containing 1,4-dihyropyridines in high yields (≤98%) and diastereoselectivity (≤10:1 dr), along with excellent enantioselectivity (typically >99% ee).… read more here.
