Abstract :
The enantioselective addition of lithioethenes to aldehydes was studied. Such asymmetric approach of the hydroxyvinylation is reported for the first time with promising ee, (up to 70% at -78 °C in THF), using mixed aggregates of the vinyllithium species and a chiral lithium amide.
Keywords :
chiral lithium amide , asymmetric vinylation , mixed aggregates vinyllithiums
