The reaction of 4-phenyl-1-butene (XX) with hypophosphorous acid gives 4-phenylbutylphosphinic acid (XXI), which is condensed with chloroacetic acid (XXII) yielding 2-[hydroxy(4-phenylbutyl)phosphoryl]acetic acid (XXIII). The esterifica-tion of (XXII) with benzyl alcohol affords the benzyl acetate (XXIV), which is esterified at the OH group of the phosphinic acid with 2-methyl-1-(propionyloxy)propyl chloride (XXV) giving the completely esterified derivative (XXVI). The debenzylation of (XXVI) with H2 over Pd/C yields the acetic acid derivative (XXVII), which is submitted to optical resolution affording the desired (S)-isomer (XXVIII). Finally, this compound is condensed with the desired intermediate trans-4-cyclohexyl-L-proline (XI) by means of CDI and NaOH.
