Total synthesis of 3,4-dihydroxyprolines, d-threo-l-norvaline and (2S,3R,4R)-2-amino-3,4-dihydroxytetrahydrofuran-2-carboxylic acid methyl ester

The Henry reaction between d-glyceraldehyde and ethyl nitroacetate allowed the practical development of a diastereoselective synthesis of 3,4,5-trihydroxy-2-nitropentanoic acid esters, which were reduced to polyoxamic acids, which were used in a new diastereoselective synthesis of 3,4-dihydroxyprolines and new enantioselective syntheses of d-threo-l-norvaline and (2S,3R,4R)-2-amino-3,4-dihydroxytetrahydrofuran-2-carboxylic acid methyl ester.
