Abstract
A convenient synthesis of novel 6-disubstituted 5-oxomorpholine-3-carboxylate derivatives (5) by stereoselective cyclization of Δ 1 -dehydrodipeptides, Boc-ΔVal-L-AA-OMe (AA=Ser, Thr, HyVal) with t-BuOCI or N-halosuccinimide is described. Furthermore, the configuration of 5 was determined by single crystal X-Ray analysis.
