β¦ Synopsis
An Enantioselective Synthesis of Natural (-)-Huperzine A via Cinchona Alkaloid Promoted Asymmetric Michael Reaction.
-An improved synthesis of the title compound is developed via the known intermediate (+)-(III) derived from the Ξ²-keto ester (I). After one recrystallization (+)-(III) is obtainable with 99% e.e. The synthesis of the enantiomer (-)-(III) is also possible by this method using (+)-cinchonine.
