A straightforward synthesis of (2S,3R)-3-hydroxyproline and trans-(2R,3S)-2-hydroxymethyl-3-hydroxypyrrolidine
摘要:
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.
