    • Initially formed triene as IV by the ring opening of 6 was not detected All new compounds were fully characterized by spectroscopic means and combustion analysis. For details, see ESI Due to its high reactivity, the [2+2] cycloadduct easily isomerized to the corresponding ring opened product during purification For the conrotatory ring opening of substituted cyclobutenes, outward rotation becomes more preferred, as the donor character of the substituent increases. In the case of fully oxygenated cyclobutene Aa (X=Y=OMe), one of the two methoxy groups has to rotate inward, which is energetically unpreferable. For theoretical studies on torquoselectivity, see:
