Hydroboration of β acetylenic alcohols followed by NaOH/H2O2 oxidation leads to hemiacetals of γ aldols which are easily dehydrated to 2,3-dihydrofuran compounds.The reaction gives good yields with hindered alcohols and its stereochemistry may be controlled during the organometallic synthesis of the starting alcohol.
