In the course of preparing a trimethylsilyl substituted 5-cyclodecenone through anionic oxy-Cope rearrangement of a trans-1,2-divinylcyclohexanol, it was discovered that the silyl substituent in the divinylcyclohexanol is positioned so that it destabilizes [3,3]-sigmatropic rearrangement through the normally observed chair-like transition state. In the case of the tri-n-propylsilyl derivative, oxy-Cope
