Rongxiang ChenYanwei ZhaoShangwen FangWenhao LongHongmei SunXiaobing WanPublished in: Organic letters (2018)
In this letter, an unprecedented cross-coupling reaction between copper carbene and nitroso radical has been developed. This radical-carbene coupling reaction (RCC reaction) offers a novel approach for the preparation of various isoxazolines, which features the construction of C-C, C-O, and C═N bonds in a one-pot process. The synthetic utility of our method is further enhanced by its mild reaction conditions, wide substrate scope, and simple procedures.
