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
由(+)-α-pine烯(一种容易获得的天然产物)合成了氨基醇官能化的新型手性离子液体。这些CIL作为对映选择性CC键形成相转移催化剂(PTC)的有效性已通过将二乙基锌添加到代表性的醛中得到证明,并且获得了具有良好收率和对映体过量的相应手性醇。
