Abstract
The reduction of alpha -substituted-beta -ketoam ides with either NaBH(4)or Zn(BH4)(2) yielded the respective beta -hydroxyamides in different diaster eomeric ratios. Selenocyclofunctionalization of these compounds yielded the corresponding tetrahydrofurans in good yields and the ratio of the diaster eomers were determined by Se-77 NMR.
