Gabbutt, Christopher D., Hepworth, John D., Heron, B. Mark and Thomas, Jean-Luc (1999) A novel acylative ring cleavage of benzothieno[3,2-b]pyran-4-ols: application to the synthesis of dibenzothiophenes and fused-ring derivatives. Chemical Communications (6). pp. 541-542. ISSN 1359-7345Metadata only available from this repository.
The benzothienopyranols 3, readily available from the ketone 1, are transformed to the carbamates 5 on treatment with N,N-dimethylcarbamoyl chloride, subsequent thermal electrocyclisation provides access to dibenzothiophene derivatives 6 and 11–13.
