hate. A number of synthetic routes were explored for the preparation of these targets. The successful approach involved the synthesis of a protected C1–phosphonate ester 17 via Michaelis–Arbuzov reaction, which was then hydrolysed and coupled with different amino acid esters using aldrithiol. Subsequent hydrogenolysis afforded the targets 2a–g, which were isolated as a mixture of diastereoisomers.
