Abstract

Novel methods are provided for synthesizing 2-amino-2-tetritol, by positive halogen addition to protected 1,4-dioxybutene-2 in the presence of a nitrile, resulting in addition of a halo functionality and the nitrile functionality across the double bond. Upon hydrolysis, the desired erythro-product can be obtained in stereochemically good yield.
