  Dimethylzinc-Mediated Addition of Alkenylzirconocenes to α-Keto and α-Imino Esters

  摘要：

  graphicHydrozirconation of alkynes followed by in situ transmetalation to dimethylzinc and 1,2-addition to activated ketones and N-diphenylphosphinoylimines leads to tertiary allylic alcohols and amines in high overall yield. With 8-phenylmenthol as the chiral auxiliary, si-face attack proceeds in good to excellent diastereoselectivitles.
