Dn. Moraes et al., Addition of Z-vinylic higher order cyanocuprates to enones followed by O-functionalization, TETRAHEDRON, 56(21), 2000, pp. 3327-3337
Transmetalation reaction between Z-vinylic tellurides and higher order cyan
ocuprates generated the corresponding Z-vinylic cyanocuprates. Conjugate ad
dition of these cuprates to enones followed by O-functionalization led to s
ilyl enol ethers, vinyl phosphates and vinyl triflates. The vinyl triflates
were transformed into highly unsaturated systems by coupling with alkynes
or with Z-vinyl zinc chlorides under Pd (0) catalysis. (C) 2000 Elsevier Sc
