A Cp*Co(III)-catalyzed [5+2] C-H annulation reaction of 2-vinylphenols with ynamides was developed. The reaction led to the efficient synthesis of valuable 2-aminobenzoxepines in high regioselectivity. Mild reaction conditions, good functional group tolerance, and moderate to good yields were observed The synthetic utility was demonstrated by a gram-scale synthesis and further transformations of the products. Preliminary mechanistic studies were conducted, and a possible catalytic cycle was proposed. In the experiment, the researchers used many compounds, for example, 3-(Phenylethynyl)oxazolidin-2-one (cas: 888329-88-2Computed Properties of C11H9NO2).

3-(Phenylethynyl)oxazolidin-2-one (cas: 888329-88-2) belongs to oxazolidine derivatives. Oxazolidine-based compounds have started to attract attention also in the medicinal and materials chemistry fields. As well as other multifunctional heterocyclic compounds, oxazolidine rings play an essential role in organic and medicinal chemistry, behaving, in some cases as powerful antitumor agents.Computed Properties of C11H9NO2
