Abstract

The Mitsunobu cyclodehydration of chiral phenethane-1,2-diols, readily accessed from styrene derivatives, provides the corresponding styrene oxides with high levels of stereoretention for electron-poor substrates. The combination of tricyclohexylphosphine and diisopropylazodicarboxylate in THF provides the best results.
