Article abstract of DOI:10.1016/S0040-4020(01)97206-0

Optically pure (L)-vinylglycine has been synthesised by two different methods.The first of these involves protected (L)-glutamate esters of N-hydroxy-2-seleno-pyridine.Such esters are shown to undergo the same decarboxylative rearrangement as their thio-a
