✦ Synopsis

Copper-catalyzed conjugate addition of organomanganese reagents to a, B ethylenic esters easily takes place in THF at O'C, in the presence of 3% CuCl and MejSiCI. Good to moderate yields are obtained from organomanganese reagents preparedfrom organolithium or organomagnesium compounok

Recently, we have shown that the conjugate addition of organomagnesium reagents to a, P-ethylenic esters easily

conjugate addition reaction efficiently and the butyl manganese chloride could be indifferently prepared from butyllithium or butyhnagnesium halide. As shown in Table I and II, the scope of this reaction is very broad. Thus, high yields of 1,4-addition products were obtained from a vast array of cy
