Article abstract of DOI:10.1016/S0040-4039(00)99269-4

Methoxyselenylation and methoxybromination of chiral 3-acyl-2-oxazolones with PhSeCl/MeOH and Br2/MeC(OMe)3 smoothly proceed to result in highly stereoselective formation of chiral synthons for β-amino alcohols, but with opposite ?-facial selectivity.
