We report a Ni-catalyzed process for the cross-coupling of tertiary alkyl nucleophiles and aryl bromides. This process is extremely general for a wide range of electrophiles and generally occurs with a ratio of retention to isomerization >30:1. The same procedure also accommodates the use of aryl triflates, vinyl chlorides, and vinyl bromides as the electrophilic component.
我们报告了一种用于叔烷基亲核试剂和芳基溴化物交叉偶联的 Ni 催化过程。这个过程对于范围广泛的亲电子试剂来说是非常普遍的,并且通常在保留与异构化的比率 > 30:1 的情况下发生。相同的程序也适用于使用芳基三氟甲磺酸酯、氯乙烯和溴乙烯作为亲电子组分。

This disclosure concerns the discovery of the use of fenoterol and (R,R)- and (R,S)-fenoterol analogues for the treatment of a tumor expressing a β2-adrenergic receptor, such as a primary brain tumor, including a glioblastoma or astrocytoma expressing a β2-adrenergic receptor. In one example, the method includes administering to a subject a therapeutically effective amount of fenoterol, a specific fenoterol analogue or a combination thereof to reduce one or more symptoms associated with the tumor, thereby treating the tumor in the subject.
