by the reaction of the in situ generated enantioenriched stereogenic cuprate reagent with (E)-4-bromo-1-iodo-1-trimethylsilyl-1-butene with retention of configuration. N-Boc deprotection, followed by a one-pot olefin isomerization and intramolecular amine alkylation afforded a bicyclic vinyl bromide that was converted into (+)-elaeokanine A by sequential halogen metal exchange and reaction of the organolithium
