(matrix presented) An efficient enantioselective synthesis of β,β-dialkyl-γ-substituted pantolactones has been achieved utilizing the cationic [Sc((S,S)-R-pybox)]-(Cl)2+, R = Ph (9), t-Bu (10), complex in a catalyzed aldol reaction as the key step. The pantolactone derivatives are isolated in enantiomeric excesses.
