Metal homoenolates, produced via C-C bond cleavage of cyclopropanols, have been extensively investigated as nucleophiles for the synthesis of β-substituted carbonyl derivatives. Herein, we demonstrate that zinc homoenolates can react as carbonyl-electrophiles in the presence of nucleophilic amines to yield highly valuable trans-cyclopropylamines in good yields and high diastereoselectivities.

通过环丙醇的 CC 键裂解产生的金属均烯醇化物已被广泛研究作为合成 β 取代羰基衍生物的亲核试剂。在此,我们证明了均烯醇锌可以在亲核胺的存在下作为羰基亲电试剂反应,以良好的收率和高非对映选择性产生非常有价值的反式环丙胺。GSK2879552 是一种赖氨酸脱甲基酶 1 抑制剂,目前正在临床试验中用于治疗小细胞肺癌,它是使用这种策略合成的。
