Conjugate addition of benzylamine to 2-(5H)-furanon-3-yl methanesulfonate in methanol afforded a 7:1 mixture of the trans and cis methyl N-benzyl-2-hydroxymethylaziridine-2-carboxylates 7 and 8, respectively. Treatment of 7 with benzyl alcohol in the presence of BF3. OEt2 then furnished, after hydrogenolysis, rac-cis alpha-amino-beta-hydroxy-gamma-butyrolactone (1). (C) 2000 Elsevier Science Ltd.
