《Synthesis of Benzo[b]furans by Intramolecular C-O Bond Formation Using Iron and Copper Catalysis》 was published in Organic Letters in 2020. These research results belong to Henry, Martyn C.; Sutherland, Andrew. SDS of cas: 403-33-8 The article mentions the following:
One-pot processes for the synthesis of benzo[b]furans from 1-aryl- or 1-alkylketones using nonprecious transition metal catalysts have been developed. Regioselective iron(III)-catalyzed halogenation of the aryl ring, followed by iron- or copper-catalyzed O-arylation allowed the synthesis of various structural analogs, including the benzo[b]furan-derived natural products corsifuran C, moracin F, and caleprunin B. In the experiment, the researchers used many compounds, for example, Methyl 4-fluorobenzoate(cas: 403-33-8SDS of cas: 403-33-8)
Methyl 4-fluorobenzoate(cas: 403-33-8) is an organic fluorinated building block used for the synthesis of various pharmaceutical compounds. It can be used for the preparation of Blonanserin.SDS of cas: 403-33-8
