  Ready access to enantiopure 5-substituted-3-pyrrolin-2-ones from N-benzyl-2,3-O-isopropylidene-d-glyceraldehyde nitrone (BIGN)

  摘要：

  The reaction of the lithiated salt of methyl propiolate with N-benzyl-2,3-O-isopropylidene-D-glyceraldehyde nitrone (BIGN) afforded the corresponding propargyl hydroxylamines in a stereocontrolled way depending on the nature of the Lewis acid used as an additive. Subsequent reduction of the obtained hydroxylamines provided chiral 5-substituted-3-pyrrolin-2-ones, in high overall yields. (C) 1998 Elsevier Science Ltd. All rights reserved.
