Abstract
Chromium(II) chloride-mediated coupling reactions of 1,1-dimethylethyl (S)- and (R)-4-formyl-2,2-dimethyloxazolidine-3-carboxylates [(S)- and (R)-Garn er aldehydes] (1a,b) with allyl bromides 2a-c proceeded with moderate to go od stereoselectivity to give the corresponding homoallyl alcohols 3a-d in g ood yields. The homoallyl alcohol 3b was easily transformed to (2R,3S)-3-hy droxy-2-hydroxymethylpyrrolidine 8.
