The synthesis of a large variety of enantiomericallypuresubstituted reactive cyclopentenes 16, 23, 24 and 28 have been synthesized from the readily available (−)-quinic acid 1. The straightforward strategy involves a high-yielding intramolecular aldolization-dehydration of acyclic 1,6-dialdehydes 13, 18, 19 and 27 obtained by oxidative cleavage of cyclohexanediols 5, 7, 11 and 12, using either lead
