Abstract:

Amino alcohol functionalized new chiral ionic liquids have been synthesized from (+)-α-pinene, an easily available natural product. The effectiveness of these CILs as phase transfer catalysts (PTC) in enantioselective C-C bond formation has been demonstrated through the addition of diethylzinc to representative aldehydes, and the corresponding chiral alcohols with good yields and enantiomeric excess have been obtained.
