  Chiral oxazolidinones from α-hydroxy oxazolidines: a new access to 1,2-amino alcohols

  摘要：

  N-Carbamoyl-alpha-hydroxy oxazolidines prepared from N-Boc-2-acyl oxazolidines or N-Boc-2-alkenyl oxazolidines, using phenyl glycinol as the chiral source, are converted into bicyclic oxazolidinones. Reactions of these compounds with different nucleophiles under conditions suitable for the production of N-acyliminium ions were studied. Allylsilane reacted very stereoselectively in all cases, and this reaction provides a new flexible entry for the preparation of enantiopure syn-2-amino alcohols, possibly bearing an additional stereocenter ex to the hydroxyl moiety.

  Regio- and Stereocontrolled Formation of Chiral Epoxy Oxazolidines via Bromocarbamation of N-Boc Alkenyl Oxazolidines. Application to Asymmetric Synthesis

  摘要：

  Treatment of alpha-alkenyl N-Boc oxazolidines with N-bromosuccinimide leads to epoxy oxazolidines via a bromocyclocarbamation reaction which is completely stereoselective. Action of sodium azide an these epoxides, followed by a few functional group manipulations, eventually affords chiral beta-amino alcohols which are intermediates for the enantioselective synthesis of bioactive products: the anti side chain of taxol and a hydroxyethylamine isostere. Both the bromocarbamation cyclization and the nucleophilic cleavage of epoxides are totally regioselective. AM1 calculations suggest that this selectivity is controlled by the positive charge distribution at the electrophilic centers.
