Abstract
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 conclusive evidence on the absolute configuration of calyculins.
