A convenient method for the stereospecific synthesis of (E)-3-alken-1-ols utilizing the ring-opening reaction of 2,3-dihydrofuran with organocuprates.

(E)-3-Alken-1-ols were stereospecifically synthesized in good yields utilizing the regioselective nucleophilic ring-opening reaction of 2,3-dihydrofuran with several kinds of organocuprates under mild conditions.
