Abstract
Improved synthetic methods for the preparation of three differently protected (2S,4R)-4-hydroxyornithines (10, 16, 24) have been developed which obviously can be used for the construction of the other stereoisomers. Formation of the corresponding α, β-didehydroamino acid derivatives (4, 15, 22) and their enantioselective hydrogenation are the characteristic steps of these syntheses.Keywords
