Dehydroamino acids are often found in nitrogen-containing natural products and widely utilized as a useful intermediate for the synthesis of nitrogen-containing organic molecules. In this article, we would like to report our recent efforts toward development of the stereoselective syntheses of α,β -dehydroamino acids and its application to the synthesis of nitrogen containing natural products and biologically active molecules. We developed a new olefination reagent,（diphenylphosphono）glycine esters, which allowed smooth condensation with aldehydes to provide E-dehydroamino acids in a stereoselective manner. The new method was successfully applied to the stereoselective synthesis of dehydroisoleucine and the tripeptide side chain of phomopsin A. Stereoselective synthesis of （2S,6R）-diamino（- 5R,7）-dihydroxy-heptanoic acid, 2,6-diaminosuberic acid, and kaitocephalin via hydrogenation of dehydroamino acid moieties are also described.
