摘要

The rate of the methylenecyclopropane rearrangement is remarkably enhanced by the 1, 6- methano [10] annulene group, which greatly stabilizes the biradical intermediate. The diastereomeric products argue against a concerted rearrangement mechanism and support a stabilized biradical intermediate that lives long enough to undergo rotation before ring closure.
