In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Visible-Light-Mediated Addition of Phenacyl Bromides onto Cyclopropenes, published in 2017-07-07, which mentions a compound: 65438-97-3, mainly applied to oxonaphthaleneacetate oxobenzo fused heterocyclylacetate chemoselective preparation; photochem addition cyclization aryl bromomethyl ketone cyclopropenecarboxylate ring opening; iridium photocatalyst addition cyclization aryl bromomethyl ketone cyclopropenecarboxylate; nonracemic cyclopropene stereoselective photochem addition cyclization phenacyl bromide, Recommanded Product: 65438-97-3.
In the presence of the photocatalyst fac-Ir(ppy)3 (ppy = 2-pyridinylphenyl), K2CO3, and LiBr in DMF, aryl bromomethyl ketones such as phenacyl bromide underwent chemoselective photochem. addition and cyclization reactions with cyclopropenecarboxylates such as I under irradiation with blue LED at 0° followed by base-mediated ring opening at 60° without irradiation to give oxonaphthaleneacetates such as II and oxobenzo-fused heterocyclylacetates in 16-51% yields. Nonracemic II was prepared in 40% yield and 95:5 er by the reaction of nonracemic I (95:5 er) with phenacyl bromide. Oxonaphthaleneacetates derived from this reaction can be further converted in one or two steps to polycyclic products such as naphthopyranacetate III and benzoindeneacetate IV.
Although many compounds look similar to this compound(65438-97-3)Recommanded Product: 65438-97-3, numerous studies have shown that this compound(SMILES:CN1C(C(CBr)=O)=CC=C1), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
