Abstract

Trienyl and allenyl phenyl sulfoxides can be reduced stereospecifically with retention of configuration in good yields using tert-butyllithium with methanol (MeOH) as an internal (in situ) proton source. The method can be easily modified to give stereospecifically deuterium- labeled compounds. While simple monoene sulfoxides afford attenuated yields of reduced olefin, the method is useful for the reduction of the more sensitive and complex polyene ...
