Application

(S)-(+)-4-Penten-2-ol can be used:
  • As an intermediate in one of the key synthetic steps for the preparation of undecenolide (−)-cladospolide C.
  • To prepare a carboxamide derivative as a key intermediate for the preparation of (−)-iso-cladospolide B1.
  • To prepare S-enantiomers of hydroxyeicosa tetraenoic acid named 19-HETE.
  • To prepare an acryloyl ester derivative by reacting with acryloyl chloride, which is a key intermediate for the synthesis of parasorbic acid.
