Conclusions

  1. 1.

    We have developed a method for the preparation of condensed heterocyclic diketones of quino[3,2,1-de]acridine, benzo[ij]quinolizino[1,9,8-cdef]carbazole, and the hitherto undescribed benzo[ij]quinolizino[1,10,9-cdef]phenothiazine. The method is based on the addition of lithioarylamides to 3-lithioarynes.

  2. 2.

    We have verified the structures of the 2-(diarylamino)isophthalic acids synthesized earlier and thereby confirmed the selectivity of addition of lithioamides to 3-lithioarynes.
