Asymmetric Tandem Michael Addition-ylide Olefination Reaction for the Synthesis of Optically Active Cyclohexa-1,3-diene Derivatives
Overview
Affiliations
The reaction of a crotonate-derived chiral phosphonium salt with alpha,beta-unsaturated carbonyl compounds in the presence of Cs(2)CO(3) affords optically active cyclohexa-1,3-diene derivatives with up to 90% ee in good yields.
