Compounds of formula (I): STR1 wherein: R1 is hydrogen, alkyl, aralkyl, --CORa, --CORb, --CSRa, --CSRb, --SO2 Rb, --CONHRb, --CSNHRb, --CONRb Rb or --CSNRb Rb ; R2 is hydrogen or alkyl; R3 is hydrogen, alkylidene, substituted alkyl, or Rb ; R4 is optionally substituted alkyl, cycloalkyl, or aryl; R5 is Rb O--, Rb Rb N--, Rb HN--, aralkyloxycarbonyloxy or aralkyloxycarbonylamino, or R5 is --(CH2)p --D--(CH2)r --, where D is a single bond, carbonyl, oxygen, sulfur, --NH--, --(CH2 =CH2)-- or --NHCO--; and p and r are each 0 or an integer from 1 to 5; A is --(CH2)m --B--(CH2)n -- where B is a single bond, carbonyl, oxygen, sulfur, --NH--, --(CH2 =CH2)-- or --NHCO--; and m and n are each 0 or an integer from 1 to 5; Ra is alkoxy, aralkyloxy, aryloxy or alkoxycarbonyl; Rb is optionally substituted alkyl, cycloalkyl, heterocyclic, aryl or arylalkenyl; and pharmaceutically acceptable salts and esters thereof and pro-drugs therefor, have the ability to inhibit the activity of HIV protease and may thus be used for the treatment and prophylaxis of AIDS.

A stereocontrolled synthesis of (2S,3R)-3-hydroxyproline 1, and trans-(2R,3S)-2-hydroxymethyl-3-hydroxypyrrolidine 2 has been achieved in 21% and 38% yield via the homochiral 4,5-disubstituted oxazolidin-2-one 3. The trans relationship in 2 has been introduced by a modified Mitsunobu reaction.
