Chiral primary amino alcohol organobase catalysts for the asymmetric Diels-Alder reactions of anthrones with maleimides

Abstract Simple chiral triethylsilyl-amino alcohol organocatalysts containing a bulky triethylsilyl group on the oxygen atom at the γ-position were designed and synthesized as new organocatalysts for enantioselective Diels–Alder reactions of anthrones with maleimides to produce chiral hydroanthracene Diels–Alder adducts in up to 99% yield and with up to 94% ee.
