Serine derived aziridine 15 was successfully ring-opened with amino acid esters to give diaminopropionic acid derivatives in excellent yield and regioselectivity. These compounds were cyclised to form the corresponding β-lactams in good overall yield. One example was fully deprotected to give target compound 1 (n = 1, R = Me) in excellent yield.
