  Oxadiazinones as chiral auxiliaries: increased diastereoselectivities in the glycolate aldol reaction of oxadiazinones

  摘要：

  Glycolate aldol reactions were conducted using a (1R,2S)-norephedrine based N-4-isopropyloxadiazinone as a chiral template to afford aldol adducts 8a-h. The yields ranged from 57% to 99% while the diastereoselectivities ranged from 94:6 to 99:1. Adduct 8a was hydrolyzed to afford the oxadiazinone auxiliary and P-hydroxyacid 9, which was converted to the known methyl (2S,3R)-2,3-dihydroxy-3-phenylpropionate 12 with 95% ee as determined by chiral HPLC.
