A one-pot reaction to synthesize functionalized 2H-azirines through visible-light-mediated ring contraction and olefin metathesis of isoxazoles is described. Hoveyda-Grubbs II catalyst was found to function as a photocatalyst for these transformations, allowing these processes to be carried out in a one-pot manner. This study offers a new entry for the application of Grubbs catalysts as efficient photocatalysts and the possibilities of carrying out other photoreactions and olefin metathesis in a one-pot process. In the experiment, the researchers used many compounds, for example, 3-(tert-Butyl)isoxazol-5-amine (cas: 59669-59-9HPLC of Formula: 59669-59-9).
3-(tert-Butyl)isoxazol-5-amine (cas: 59669-59-9) belongs to isoxazole derivatives. Isoxazoles also form the basis for a number of drugs, including the COX-2 inhibitor valdecoxib (Bextra) and a neurotransmitter agonist AMPA. Isoxazoles are potent isosteres of pyridine and have been found to inhibit voltage-gated sodium channels for pain control, for the construction of tetracycline antibiotic derivatives, and as a therapeutic agent for depression.HPLC of Formula: 59669-59-9
