Desymmetrization of Cyclohexadienones via Asymmetric Michael Reaction Catalyzed by Cinchonine-Derived Urea
摘要:
Desymmetrization of cyclohexadienones bearing a bisphenylsulfonyl methylene group via asymmetric Michael reaction catalyzed by cinchonine-derived urea was realized to afford a series of highly enantioenriched polycyclic cyclohexenones in high yields and ee's.
