摘要：

A new chiral Lewis acid catalyst, [BINOL-Zr(OiPr)(2)], is prepared from (R) or (S)-BINOL and commercially available Zr(OiPr)4 . iPrOH; it efficently promotes the enantioselective allylation of aldehydes by allyltributyltin in shorter rimes and at lower temperatures with respect to related catalysts.
