The nucleophilic ring opening of gem-dicyanoepoxides by LiBr or Li 2 NiBr 4 , in the presence of hydroxylamine derivatives leads to new α-halo hydroxamic acids. These compounds has been used in the synthesis of αfunctionalized hydroxamic acids, α-hydroxy and α-amino acids in good yields.

## Abstract A synthesis of α,β‐dehydroamino acid derivatives **12** is described, which is of possible general applicability and might be useful for the preparation of peptides which have such a moiety in their sequence. In addition, several didehydrodioxopiperazines (**13–17**) have been prepared.
