摘要:
Chirality transfer from asymmetric ligands to the diene in (eta(4)-cis-1,2-divinylcyclohexane) rhodium complexes has been observed, leading to a slight excess of one of the two enantiomeric chair conformations of the cyclohexane ring. The importance of this phenomenon for the palladium-catalyzed oxidative cyclization of (cis-1,2-divinylcyclohexane) using chiral carboxylates as nucleophiles is discussed.
