Derivatives of 1,3-thiazolidin-2,4-dione appended to biphenyl ring viz., 7-9, 16-18 were prepared. The newly synthesized compounds were confirmed by IR, NMR (1H and 13C) MS and elemental analyses. Single crystal X-ray diffraction study was carried out for one of the final compounds 9.

One-pot synthesis and UV-Visible absorption studies of novel tricyclic heterocycle tethered Xanthene-1,8-diones
Thirumal Yempala Balasubramanian Sridhar Srinivas Kantevari
A series of new tricyclic heterocyclic xanthene-1,8-diones tethered with chromophoric dibenzo [𝑏 , 𝑑]furan, dibenzo[𝑏 , 𝑑]thiophene and 9-methyl-9$H$-carbazoles were synthesized through one-pot condensation of dibenzo[𝑏 , 𝑑]furan-2-carbaldehyde, dibenzo[𝑏 , 𝑑] thiophene-2-carbaldehyde and 9-methyl-9𝐻-carbazole-3-carbaldehyde with cyclic 1,3-dicarbonyls in the presence of recyclable PPA-SiOM2 catalyst under solvent-free conditions. Further, UV-Visible absorption properties of all the synthesized compounds were investigated in CHCl3, THF and acetonitrile.
