2,3-Dihydroxy-4-dimethylamino-5-methoxypentanoic acid (2) with (2R,3R,4R)-configuration has been stereoselectively prepared from (S)-pyroglutaminol (3) and revealed to be the enantiomer of the compound derived from calyculins (1), which provides the conclusicve evidence on the absolutr configuration of calyculins.
