Abstract Newmethod for one-pot preparation of cis 1,2-cyclopentanediols frombicyclicketals in the 6,8-dioxabicyclo[3.2.1]octane series is described. Bicyclicketals are refluxed for 1h with AlCl3 (3eq.) in AcOH and further refluxed for 60h after addition of Zn(8eq.) to give cis 1,2-cyclopentanediols in good yield.
