Anomalous syn-diastereoselectivity of indium-mediated coupling of aldehydes with bromides Z-3b and E-3b is reported. The reaction afforded high syn selectivity regardless of the allylic bromide geometry. Preliminary studies on the enantioselective indium-mediated allylation were attempted and found to give the desired products in moderate yield with high syn selectivity and enantioselectivity.
异常顺醛与溴化物铟-介导的偶联的-diastereoselectivity ž -图3b和ë -图3b报道。不管烯丙基溴的几何形状如何,该反应均提供高的顺式选择性。尝试了对映选择性铟介导的烯丙基化的初步研究,发现以中等收率获得了所需的产物,同时具有高的顺式选择性和对映选择性。
