Diastereospecific formal synthesis of (2R,3S)-2-amino-tetradeca-5,7-dien-3-ol isolated from Xestospongia sp.
摘要:
Stereospecific synthesis of a common precursor of several acyclic (2R,3S)-2-amino-3-ols from marine origin, especially of (2R,3S)-2-amino-tetradeca-5,7-dien-3-ol isolated from Xestospongia sp., is described starting from the versatile epoxide 10. (C) 2001 Elsevier Science Ltd. All rights reserved.

The first enantioselective synthesis of (2S,3S,4R)-3,4-dihydroxyglutamic acid was efficiently achieved in six steps from (3R,4R,5R)-1-tert-butoxycarbonyl-3,4-epoxy-5-(1-ethoxy)ethoxymethyl pyrrolidin-2-one 4 derived from (S)-pyroglutaminol.
