The First Transformation of Aliphatic α,β-Epoxyamides into α-Hydroxyamides
摘要:
[GRAPHICS]A general synthesis of aliphatic alpha-hydroxyamides with total regioselectivity by a reductive cleaveage of the C-beta-O bond of aliphatic alpha,beta-epoxyamides, promoted by samarium diiodide and MeOH, is described. The treatment of enantiopure aliphatic alpha,beta-epoxyamides afforded enantiomerically enriched aliphatic alpha-hydroxyamides. A radical mechanism has been proposed to explain this reaction.
