摘要

Lewis acid mediated reactions of organocopper reagents with various kinds of cr,@- unsaturated carbonyl derivatives are described. RCu. BF3, as well as RCu-other Lewis acid systems, is useful for the conjugate addition to the+ unsaturated ketones and esters, whose double bonds are sterically crowded. Certain a,@-unsaturated carboxylic acids also undergo a 1, Caddition through this reagent. Methyl sorbate undergoes a 1, 4-addition via ...
