Fused α-acyloxycyclobutanones, whose conformation and stereochemistry have been unambiguously established by X-ray analysis, undergo an unusual displacement with methoxide as nucleophile to produce α-methoxycyclobutanones. The success of this reaction, which suggests the intermediacy of an oxyallyl cation, is highly dependent on conformational and steric factors.
