K. Nordstrom et al., ENANTIODIFFERENTIATION OF OLEFINIC GROUPS IN CIS-1,2-DIVINYLCYCLOHEXANE, Journal of organometallic chemistry, 525(1-2), 1996, pp. 233-238
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 pal
ladium-catalyzed oxidative cyclization of (cis-1,2-divinylcyclohexane)
using chiral carboxylates as nucleophiles is discussed.
