Aspects stéréochimiques du réarrangement de Cope de monoesters d'hexadiènes-1,5
Written by sctunisie no commentsThe Z/E olefinic bond ration of enol ethers obtained by Oxy-Cope rearrangement of hetero-substituted 1,5-hexadienes reveals that the reaction is not governed by the free energy change for the conversion of a substituent from the equatorial to the axial position in the chair transition state but rather by the relative thermodynamic stability of the isomers Z and E.
