Description

Application

(R)-3,3′-Bis(triphenylsilyl)-1,1′-bi-2-naphthol reacts with trimethylaluminum to form a chiral organoaluminum reagent, which can catalyze the asymmetric Diels-Alder reaction of cyclopentadiene and methyl acrylate to form the corresponding Diels-Alder adduct.

Precursor to a chiral Bronsted acid (674745) used to catalyze an enantioselective aza Diels-Alder reaction providing bicyclic lactams. Rare earth metal complexes of this chiral binapthol catalyze an intramolecular hydroamination of amino olefins leading to chiral pyrrolidines.
