A chemoselective tandem reaction of a multi-reactive, two electrophile + two nucleophile, system is reported. An allylation/cross-coupling process of a haloaryl aldehyde, an aryl BPin, and an allyl BPin can be controlled using a temperature gradient to overcome natural reactivity profiles and allow two sequential chemoselective C-C bond formations without intervention. This process offers efficient
报道了多反应性的两个亲电试剂+两个亲核试剂系统的化学选择性串联反应。可以使用温度梯度来控制卤代芳基醛,芳基BPin和烯丙基BPin的烯丙基化/交叉偶联过程,以克服自然的反应活性,并允许两个连续的化学选择性CC键形成而无需干预。此过程可有效访问包括药品和天然产品支架在内的一系列功能化产品。
