Silylcupration reaction of 1,3-dienes with a cyanocuprate reagent, PhMe2SiC
uCNLi, followed by an electrophilic trapping has been reported for the firs
t time. The use of allylic phosphates as electrophiles resulted in a highly
regioselective reaction with overall 1,4-addition of the silyl and allyl m
oieties across the diene.
