Simple chiral TES-amino alcohol organocatalysts containing a bulky
silyl [triethylsilyl: TES] group on oxygen atom at γ-position were designed and
synthesized as new organocatalysts for the enantioselective Diels-Alder (DA) reaction
of anthrones with maleimides to produce chiral hydroanthracene DA adducts (up to
99% yield with up to 94% ee).
