Description

Application

Precursor to a chiral Bronsted acid (680184) used to catalyze an enantioselective aza Diels-Alder reaction providing bicyclic lactams.[1] Rare earth metal complexes of this chiral binapthol catalyze an intramolecular hydroamination of amino olefins leading to chiral pyrrolidines.[2]

Enantioselective direct aza hetero-Diels-Alder reaction catalyzed by chiral Brønsted acids.

Hua Liu et al.

Organic letters, 8(26), 6023-6026 (2006-12-15)

[Structure: see text] The first chiral Brønsted acid-catalyzed asymmetric direct aza hetero-Diels-Alder reaction has been described. The phosphoric acids, prepared from binol and H8-binol derivatives, have shown catalytic ability for the reaction of cyclohexenone with N-PMP-benzaldimine. A chiral phosphoric acid
