Naidu, Bandameeda Ramesh;Lakshmidevi, Jangam;Venkateswarlu, Katta;Lakkaboyana, Sivarama Krishna research published 《 Highly economic and waste valorization strategy for multicomponent and Knoevenagel reactions using water extract of tamarind seed ash》, the research content is summarized as follows. The application of solid organic waste-originated products in the preparation of synthetically and biol. significant compounds in aqueous media or pure water is a highly desired task in chem. synthesis that shows an effective solution to the circular economy and sustainable environment. In this article, we describe our research on the development of highly economic and sustainable protocols for the synthesis of biol. important oxygen-heterocycles (using a multicomponent reaction) and synthetically important olefins (via the Knoevenagel condensation reaction) using water extract of tamarind seed ash (WETS) as catalyst and aqueous reaction medium. The reactions are carried out at room temperature (RT) under toxic/problematic/volatile organic solvent-free conditions. Products of the current methods have been purified by using recrystallization technique. WETS was characterized from its FTIR, powder XRD, SEM, and EDAX data. Problematic and non-renewable solvents were avoided throughout the process from their synthesis to purification The utilization of solid organic waste-originated catalyst and aqueous media, avoid of non-renewable substances as catalysts, media, separation solvents and promoters, and unobligating heating conditions can surely attract the attention of chemists towards exploring the waste-based products in chem. transformations.

Murayama, Nina;Hao Jorolan, Joel;Minoura, Mao;Nakano, Haruyuki;Ikoma, Tadaaki;Matano, Yoshihiro research published 《 9-(Diphenylphosphoryl)-10-(phenylethynyl)anthracene Derivatives: Synthesis and Implications for the Substituent and Solvent Effects on the Light-Emitting Properties》, the research content is summarized as follows. Herein, we report a series of 9-(diphenylphosphoryl)-10-(phenylethynyl)anthracenes (DPPPEAs) as novel fluorescent 9,10-disubstituted anthracene derivatives The DPPPEAs were prepared by Sonogashira coupling of (10-bromoanthracen-9-yl)diphenylphosphine oxide with terminal arylacetylenes, and their structures were fully characterized. UV/Vis fluorescence spectroscopy and theor. calculations were used to evaluate substituent effects on fluorescence properties of DPPPEAs. The nature of emissive excited state of DPPPEAs was found to vary greatly depending on the substituent, solvent, and temperature Unsubstituted DPPPEA emitted intense fluorescence from locally excited (LE) state, whereas donor-acceptor (D-A) type DPPPEAs substituted with diphenylamino groups showed strong solvatofluorochromism derived from the charge-transfer (CT) state. Notably, carbazolyl derivatives exhibited fluorescence from LE hybridized with CT state. The disappearance of CT emission in rigid media suggests that solvent reorganization plays a crucial role in producing large Stokes shifts of D-A type derivatives The DPPPEAs have also been found to function as annihilators in porphyrin-sensitized triplet-triplet annihilation processes.

Moolman, Chantalle;van der Sluis, Rencia;Beteck, Richard M.;Legoabe, Lesetja J. research published 《 Exploration of benzofuran-based compounds as potent and selective Plasmodium falciparum glycogen synthase kinase-3 (PfGSK-3) inhibitors》, the research content is summarized as follows. A series of benzofuran-based compounds I [R¹ = H, HO, MeO, Cl; R² = H, HO, MeO, (₅H₂C)N; R³ = H, HO, MeO, Br; R⁴ = H, MeO, Cl; R⁵ = H, F, NC, MeO, Cl, Br] was synthesized and evaluated as inhibitors of recombinantly expressed and purified PfGSK-3 and human glycogen synthase kinase-3 beta (HsGSK-3β). Of this series, five compounds I [R¹ = H; R² = H, MeO; R³ = H, MeO; R⁴ =H, MeO, Cl; R⁵ = H, F, NC, Cl] preferentially inhibited PfGSK-3, with four of these compounds exhibiting IC₅₀ values in the sub-micromolar range (0.00048-0.440μM). Evaluation of the structure-activity relationships required for PfGSK-3 selective inhibition indicated that a C6-OCH₃ substitution on ring A was preferred, while the effect of the ring B substituent on activity, in decreasing order was: C4′-CN > C4′-F > C3′-OCH₃ > C3′,4′-di-Cl. To date, development of PfGSK-3 inhibitors was limited to the 4-phenylthieno[2,3-b]pyridine class.

This paper reports a simple approach for the preparation of new photo-active conjugated porous polymers (CPPs) based on phenanthrene building blocks with a high Brunauer-Emmett-Teller (BET) surface area. Starting from 2,7-diiodophenanthrene-9,10-dione and its bis-dioxolane derivative with different alkynyl comonomers, we prepared a series of CPPs by C-C Sonogashira-Hagihara coupling activated by microwaves. Moreover, we demonstrated that these functionalized CPPs after hydrolysis to the corresponding diketones show much higher BET surface areas than those obtained directly from the phenanthrene-9,10-dione monomer. Reaction of diketone-hydrolyzed polymers with 2,4-difluoro-6-hydroxybenzaldehyde yields phenantroimidazole derivatives Indeed, these structurally robust polymers result in efficient, recyclable, heterogeneous photo-organocatalysts for the aza-Henry reaction (C-H functionalization) induced by visible-light irradiation
