The conjugate addition of organomagnesium reagents to α, β-ethylenic esters is performed in THF, at room temperature (30 min to 1.5 h), in the presence of CuCl (3%) and Me3SiCl (1.2 eq.). Good yields of 1,4-addition products are obtained according to this very simple procedure.
在室温下(30分钟至1.5小时),在CuCl(3%)和Me 3 SiCl(1.2当量)存在下,在THF中将有机镁试剂共轭添加到α,β-乙烯酯中。根据该非常简单的方法,获得了1,4-加成产物的良好收率。
