Stereoselective Synthesis of Optically Active E- and Z-Homoallyl Alcohols from Epoxides
摘要:
Optically active E- and Z-homoallyl alcohols were prepared by Wittig and Warren olefination starting from optically active 3-hydroxyalkyltriphenylphosphonium salts, which were obtained by the reaction of epoxides with methylenetriphenylphosphorane and dibenzoyltartric acid followed by optical resolution.
