Croatica Chemica Acta Vol. 95, No. 1, 2022
Visible light mediated synthesis of benzoxazoles from benzanilides under an air atmosphere at room temperature is reported using eosin Y as an organophotoredox catalyst by functionalization of C–H/C–O bond formation. This methodology accepts a broad range of functional groups and affords the benzoxazoles by transition-metal-free organic photoredox catalysis under very mild conditions.

eng Synthesis and potential cytotoxic activity of some new benzoxazoles, imidazoles, benzimidazoles and tetrazoles
Acta Pharmaceutica Vol. 63, No. 2, 2013
The present work deals with the synthesis of some novel heterocyclic compounds such as benzoxazoles 2, 7, 13 and 19, imidazoles 3, 8, 14 and 20, benzimidazole 4, 9, 15 and 21, tetrazoles 10, 16, and 22. The synthesized compounds were characterized by IR, 1H NMR, mass spectrometry and elemental analysis. The compounds were evaluated for cytotoxicity against human cancer cell line such as, MCF-7 (breast cancer) and HT-29 (colon cancer) by MTT assay method. Among the tested compounds, compounds 4,4’-sulfonylbis(N-(2-(1H-benzo[d]imidazol-2-yl)ethyl...
