Sustainable approaches for the synthesis of 2-substitutedbenzothiazoles are sought after for their use in organic chemistry, bioorganic chemistry, and industrial applications. Here, we described a visiblelight-drivenphotoredox catalytic cyclization of thioanilides to afford 2-substitutedbenzothiazoles using riboflavin as a photocatalyst, where oxygen is used as a clean oxidant and ethanol as a
