Four Chiral Centers in a One-Pot Procedure. Analogues of Isosorbide. -Lithiation of the previously reported diene (I) and following reaction with acetone leads to the diol (III) which can be directly cyclized to isosorbide analogue (IV) under Sharpless conditions. A racemic analogue can be obtained
