通过无过渡金属的一锅两步程序制备了各种官能化三芳基甲烷和1,1-二芳基烷烃衍生物,其中包括各种二乙酸苯亚缩酯与有机锌试剂的反应。通过将溶剂从 THF 更改为甲苯,可以实现顺序交叉偶联,并提出了两步 S N 1 型机理,并通过实验研究证明了这一点。该方法的合成效用通过几种生物学相关分子的合成得到进一步证明,例如抗结核剂、抗乳腺癌剂、鞘氨醇-1-磷酸(S1P)受体调节剂的前体和FLAP抑制剂。

We report a five-step synthesis of the biologically important 1,1-diarylalkane 1, a potential5-lipoxygenase activating protein (FLAP) inhibitor that was synthesized previously in 12 steps. In this synthesis, we apply a three-component alkene dicarbofunctionalization reaction as a key final step to assemble the potential FLAP inhibitor 1 from commercially available starting materials. In addition,
