摘要

3500 J. Org. Chem., Vol. 57, No. 12, 1992 pears to be an example of an electrocyclic ring-~ pening.~ There are apparent examples of cyclopropyl anions undergoing thermally allowed conrotatory ring-openings? light-promoted disrotatory ring-openings? and thermally forbidden disrotatory ring-openings. e Since the rate of rotation of the allyl bond in the allyl anion is fast relative to the ring-opening, the sense of the ring-opening is difficult to ...
