Lithium diorganocuprates add across the triple bond of substituted and non-substituted acetylenic acetals and ketals to give dialkenylcuprates, which can be decomposed into alkoxyallenes or may be trapped with a variety of electrophiles, such as alkyl, alkenyl, alkynyl and aryl halides. They may also undergo conjugate addition to α-βunsaturated esters and ketones. The method is used for the synthesis
二有机辛酸锂跨取代的和未取代的乙缩醛和缩酮的三键加成,得到二烯基铜酸酯,它们可以分解成烷氧基丙二烯或被多种亲电试剂捕获,例如烷基,烯基,炔基和芳基卤化物。它们也可以进行共轭加成到α-β不饱和酯和酮上。该方法用于合成(±)-甘露酮,纯香叶醛和(E,Z)2,4-二烯醛。
