  SmI2-coupling reaction of chiral non-racemic α-bromo-α′-sulfinyl ketones with imines: synthesis of enantiomerically pure 2-methyl-3-amino-1-ol moieties

  摘要：

  Chiral non-racemic alpha-bromo-alpha'-sulfinyl ketones were shown to react with imines in the presence of SmI2 to give the corresponding 1,3-aminoketo derivatives with good syn-diastereoselectivity. Further reduction of these adducts either with DIBAL-H only or with DIBAL-H in the presence of Yb(OTf)(3) afforded syn- and anti-2-methyl-3-amino-1-ol moieties, respectively, in good yields and diastereoselectivities.
