Silylcupration of 1,3-dienes followed by an electrophilic trapping reaction
1Department of Organic Chemistry, Arrhenius Laboratory, Stockholm University, SE-10691 Stockholm, Sweden.
Abstract:
[see reaction]. Silylcupration reaction of 1,3-dienes with a cyanocuprate reagent, PhMe2SiCuCNLi, followed by an electrophilic trapping has been reported for the first time. The use of allylic phosphates as electrophiles resulted in a highly regioselective reaction with overall 1,4-addition of the silyl and allyl moieties across the diene.

Conformation
The simplest example of a diene is 1,3-butadiene, an acyclic conjugated π system. At room temperature, the molecule exists as a mixture of s-cis and s-trans conformers by virtue of rotation around the carbon–carbon single bond. Although the s-trans isomer is more stable, the...
