The enantioselective allylation of aldehydes using a variety of β-amido functionalized allyltributylstannanes proceeded smoothly with good to high yields and enantioselectivities in the presence of 10 mol % of a chiral catalytic complex prepared from In(OTf)3 and 2,6-bis[(S)-4-isopropyloxazolin-2-yl]pyridine (S)-i-Pr-pybox}, providing the corresponding chiral γ-hydroxy amides.
在由In(OTf)3和2,6-双[[ S)-4-异丙基恶唑啉-2-基]吡啶(S)-i -Pr-pybox},提供相应的手性γ-羟基酰胺。
