Polyphenyl derivativesQ 0700 Diastereoselective Oxidative Carbon—Carbon Bond Formation via Silyl Bis-enol
Ethers. — A variety of symmetrical and unsymmetrical substrates undergoes formal dimerization and cross-coupling, respectively. A higher steric hindrance of the starting material results in a higher stereoselectivity. Coupling of meso silyl bis-enol ether (XIII), derived from (R)- and (S)-carvone, furnishes the racemic product (XIV) as the main component. — (AVETTA, C. T. J.; KONKOL, L. C.; TAYLOR, C.
