dehydration methodologies to obtain N-ethyl-α, β-dehydroamino acidderivatives. The application of this N-alkylation procedure to several methylesters of β,β-dibromo and β-bromo, β-substituteddehydroaminoacids protected with standard amine protecting groups was subsequently reported. The corresponding N-ethyl, β-bromodehydroaminoacidderivatives were obtained in fair to high yields and some were used
