The structure of the acetylenic amino acid, which, on catalytic hydrogenation yields homoleucine as the only product whose structure is provided, is to be determined. Concept introduction: Hydrogenation of alkynes in the presence of the customary metal catalysts consumes two molar equivalents of H 2 to give alkanes. Carboxylate group is not reduced in this reaction. During hydrogenation, two hydrogen atoms get attached to each triple bonded carbon atom in the alkyne. The triply bonded carbon atoms in an alkyne group are bonded to only one other atom.
