The aluminum hydride reduction of 3,4-epoxycyclopentene to 3-cyclopentenol has been previously observed1 and the complete regiospecificity of the reaction is confirmed here. A mechanism is proposed involving initial complexation of the aluminum hydride anion with the double bond followed by hydride transfer to the 3-Carbon. Analysis of the atomic charges determined from semiempirical electrostaic potentials support the proposed mechanism. Spectroscopic analysis of the resultant alcohol indicates the presence of an O-H''''''π intramolecular hydrogen bonded interaction.
