carbon has been optimized. After conversion of aminophosphonates to their oxalte salts, the absolute configuration of the main diastereoisomer has been determined by X-ray analysis. α-Fluorinated-γ-aminophosphonates can be used as convenient precursors (“building blocks”) in the preparation of medicinally important analogues. As an example preparation of dipeptide analogues of α-fluorinated-γ-aminophosphonates
