The product distribution obtained from the TiCl4 initiated intramolecular isomerizations of 4methoxyphenyland trimethoxyphenyldioxolanes at -78 C, -30 C and 0 C provided insights into the important regiochemical role played by these groups in such Mukaiyamatype rearrangements through their resonance effects on the aryl ring of the dioxolanes.
