Synthesis and antitubercular evaluation of novel dibenzo[b,d]thiophene tethered imidazo[1,2-a]pyridine-3-carboxamides

A series of novel dibenzo[b,d]thiophene tethered imidazo[1,2-a]pyridine carboxamides 7a-s were designed and synthesized. The required building block, 2-dibenzo[b,d]thiophenyl imidazo[1,2-a]pyridine carboxylic acid (5) was synthesized from commercial dibenzo[b,d]thiophene in good yields following five-step reaction sequence. The desired carboxamides 7a-s was prepared through coupling of acid 5 with various benzyl amines. All the new analogues 7a-s was characterized by their NMR and mass spectral analysis. Among nineteen new compounds 7a-s screened for in vitro antimycobacterial activity against Mycobacterium tuberculosis H37Rv, three compounds 7k (MIC: 0.78 μg/mL); 7e and 7n (MIC: 1.56 μg/mL) were identified as potent analogues with low cytotoxicity. The results reported here will help global efforts for identification of potential lead antimycobacterial agents.

A luminescent Eu(III) complex based on 2-(4′, 4′, 4′-trifluoro-1′, 3′-dioxobutyl)-dibenzothiophene for light-emitting diodes

Complex Eu(dbt)3(phen) (Hdbt = 2-(4′, 4′, 4′-trifluoro-1′, 3′-dioxobutyl)-dibenzothiophene, phen = 1,10-phenanthroline) was synthesized. The complex emits red luminescence, characteristic of the 5D0 → 7FJ (J = 0-4) emission bands of Eu3+ under near ultraviolet. A red conversion light-emitting diode (LED) device was fabricated by coating complex onto InGaN-based-LED chip that emits 395 nm ultraviolet light. When the mass ratio of the red phosphor to the silicone is 1:25, the LED device's CIE chromaticity coordinates are x = 0.5835, y = 0.2857, and the luminescence efficiency is 1.29 lm/w. All the results show that this europium complex may act as a red component in fabrication of white LEDs with high color-rendering index.

Transition-Metal-Free Diarylannulated Sulfide and Selenide Construction via Radical/Anion-Mediated Sulfur-Iodine and Selenium-Iodine Exchange

A facile, straightforward protocol was established for diarylannulated sulfide and selenide construction through S-I and Se-I exchange without transition metal assistance. Elemental sulfur and selenium served as the chalcogen source. Diarylannulated sulfides were systematically achieved from a five- to eight-membered ring. A trisulfur radical anion was demonstrated as the initiator for this radical process via electron paramagnetic resonance (EPR) study. OFET molecules [1]benzothieno[3,2-b][1]benzothiophene (BTBT) and [1]benzothieno[3,2-b][1]benzoselenophene (BTBS) were efficiently established.
