Abstract
The new copper reagents RCu(CN)Zn I · 2 BF 3 1 containing various functional groups like esters, cyanides, chlorides or enoates react with β, β′- disubstituted enones to afford the Michael adducts 4–7 in high yields (81–98%). Cyano-substituted 1,4-adducts undergo a new cyclization reaction leading to the very stable bicyclic difluoroboron enolates 11a–11c which could be converted into the bicyclic diketones 12 under mild basic conditions. The X-ray structure of 11b is reported.
