Synthesis of Enantiopure α‘-Amino α,β-Epoxy Ketones from α‘-Amino Bromomethyl Ketones

Abstract
Preparation of enantiomerically pure α'-amino α,β-epoxy ketones 2 in an efficient synthesis starting from α'-amino bromomethyl ketones 5 and the obtention of amino diepoxido 10a as synthetic application of 2 are described. We also report the generalization of the synthesis of 1-aminoalkyl halomethyl ketones to their bromo derivatives.
