چکیده
The title compound, C(19)H(26)O(8)S, has been synthesized from 2,3:4,5-di-O-isopropyl-idene-β-d-fructopyran-ose. The absolute configuration of the fused ring is confirmed by anomalous dispersion effects in the diffraction measurement. The six-membered β-fructopyran-ose ring has a twist-boat conformation with the two five-membered rings trans to each other. In the crystal, inter-molecular non-classical C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.

Prevalence to the various biological activities of imidazo[4,5-b] pyridine nucleus has promoted us for an attempt of one pot synthesis of (1H, 3H) imidazo [4,5-b] pyridines (desazopurines) as inhibitors of Lumazine synthase in M. tuberculosis (PDB 2C92). Major advantage of Lumazine synthase enzyme behind consideration as target protein in docking study is its absence in mammalian cell but prese...
