A 3-component cascade synthesis of bis(2-arylallyl) tertiary
amines from aryl iodide, allene and primary aliphatic amines is described;
chiral amines give analogous products with no detectable racemisation;
mixtures of two different aryl iodides can be utilised to give the mixed
tertiary amines as the sole, or major, product; the reaction is sensitive
to stereoelectronic effects which lead to mono(2-arylallyl) secondary
amines.
描述了一种由芳基
碘化物、烯烃和初级脂肪族胺组成的双(2-芳基烯丙基)叔胺的 3 组分级联合成法;手性胺可得到类似的产物,且检测不到外消旋化;可利用两种不同芳基
碘化物的混合物得到混合叔胺作为唯一或主要产物;该反应对导致单(2-芳基烯丙基)仲胺的立体电子效应很敏感。
