Cuprates cyanide, conjugate addition

This technique also greatly improves yields of conjugate addition of cuprates to y..[>-unsaturated esters and amides.38 Trimethylsilyl cyanide also accelerates conjugate addition.39... [Pg.488]

The treatment of one equivalent of 5-lithio-2,3-dihydro-1,4-dioxin with 0.5 equivalent of copper(I) cyanide solubilized as its lithium chloride (0.5 equiv.) complex at — 15°C affords the corresponding cyanocuprate. The reactivity of this cuprate was assessed by its conjugate addition to cyclic enones, and by nucleophilic epoxide opening the presence of boron trifluoride etherate led to enhancement... [Pg.464]
