Irradiation of arenecarbothioamides with 2-methoxyfuran in benzene solution gave arene-fused aminobenzoates in moderate yields accompanied by small smounts of arylpyrroles or arylthiophenes. In the case of 2-trimethylsiloxyfuran, arenecarbothioamides gave arene-fused aminobenzoates in good yields as sole products. It was demonstrated that certain furan derivatives are potentially useful as building blocks in photoinduced benzannulation.
