Optimization of ring-contraction of the meso enedione epoxide for chiral building block synthesis

The ring-contraction of the enedione epoxide obtained from the adduct of benzoquinone and cyclopentadiene is mainly affected by the amount of base used. Excellent yields (>80%) of the ring-contracted product were consistently obtained when the epoxide was
