Selective Metal-Controlled Synthesis of Trifluoromethylated (Indolin-2-ylidene)methyl- and Quinolin-3-ylphosphonates

Metal-catalyzed (Cu, Ag, Au) reactions of alkynylphosphonates with 1-(2-aminophenyl)-2,2,2-trifluoroethan-1-ones were developed. Terminal alkyne diethyl ethynylphosphonate reacted with ketones to give different products depending on the catalyst used. With a CuI/PPh3 catalytic system, the formation of CF3-containing indoline derivatives was observed with good yields. The use of AgSbF6 as a catalyst led to quinoline derivatives in high yields. The less reactive 2-substituted ethynylphosphonates required gold complexes as catalysts to provide the corresponding 2-aryl(alkyl) substituted 4-(trifluoromethyl)quinolin-3-ylphosphonates with good yields.

Harnessing interrupted Fischer in continuous flow: sustainable synthesis of (spiro)indolenine and (spiro)indoline privileged scaffolds

A greener and sustainable flow chemistry protocol for the synthesis of 3,3-disubstituted indolenines through interrupted Fischer indolisation reaction is described. First, two model aldehydes were reacted with phenylhydrazine in order to explore the reaction feasibility in a ‘greener’ fashion in batch mode. The best outcomes were then used as the starting point for the implementation of the reaction in continuous flow. A thorough exploration of key parameters allowed the identification of the most efficient reagent mixing mode, and the optimum temperature and residence time. The newly developed method allowed straightforward reaction channelling towards the formation of the indolenines, thus reducing the competitive formation of side products. We further broadened the scope of the conceived methodology by exploring the possibility of a heterogeneous in-line reduction of the indolenines to their indoline counterparts. This rapid approach nicely complements known batch chemistry and could facilitate synthesis and scale up of 3,3-disubstituted indolenines and indolines, offering a coupling point for additional and subsequent flow reactions for multistep syntheses for further derivatization.

Antiproliferative and apoptotic effects of indole derivative, N-(2-hydroxy-5-nitrophenyl (4 ‘-methylphenyl) methyl) indoline in breast cancer cells

Indoline derivatives functions as an inhibitors of epidermal growth factor receptor (EGFR) with the anticancer potential against various cancers. We aim to investigate anti-breast cancer effects and mechanism of action of novel indoline derivatives. Molecular docking of seven indoline derivates with EGFR revealed, N-(2-hydroxy-5-nitrophenyl (4’-methylphenyl) methyl) indoline (HNPMI) as the top lead compound. RT-PCR analysis showed the downregulation of PI3K/S6K1 genes in breast cancer cells through the activation of EGFR with HNPMI. This compound found to have higher cytotoxicity than Cyclophosphamide, with the IC50 of 64.10 mu M in MCF-7 and 119.99 mu M in SkBr3 cells. HNPMI significantly reduced the cell proliferation of MCF-7 and SkBr3 cells, without affecting non-cancerous cells, H9C2. Induction of apoptosis was analyzed by Caspase-3 and -9, DNA fragmentation, AO/EtBr staining and flow cytometry assays. A fold change of 0.218- and 0.098- for caspase-3 and 0.478- and 0.269- for caspase-9 in MCF7 and SkBr3 cells was observed, respectively. Caspase mediated apoptosis caused DNA fragmentation in breast cancer cells upon HNPMI treatment. The structural elucidation of HNPMI by QSAR model and ADME-Tox suggests, a bi-molecular interaction of HNPMI-EGFR which is related to antiproliferative and apoptotic activity. The data concludes that, HNPMI-induced the apoptosis via EGFR signaling pathway in breast cancer cells. Thus, HNPMI might serve as a scaffold for developing a potential anti-breast cancer therapeutic agent.

Computational Protocol for Precise Prediction of Dye-Sensitized Solar Cell Performance

Numerous organic dyes have been developed for dye-sensitized solar cells (DSSCs). However, theoretical screening has not played a due role in designing new dyes. It is mainly attributed that there is rarely quantitative calculation and the inaccurate estimated values for short-circuit current density (J(SC)) and open-circuit photovoltage (V-OC), especially for V-OC. In this work, V-OC is theoretically predicted by two different models for three D-pi-A organic dyes (1, 2, and 3) with the same pi bridge and acceptor as well as different donors. Although there is a slight deviation in their structures, their properties are successfully differentiated by accurate quantitative calculations. Dimethoxybenzene-substituted indoline is more suitable as donor than methoxy-substituted triphenylamine and methyl-substituted indoline when it combines with 8H-thieno [2′,3′:4,5]thieno [3,2-b]thieno [2,3-d]pyrrole (TTP) as pi bridge and cyanoacrylic acid as acceptor. The properties of the donor are not only related to the core group but are also determined by the substituted group. A less than 10% deviation between theoretical and experimental results is an assurance to perform a reasonable prediction for photocurrent-photovoltage.

Chiral bifunctional sulfide-catalyzed asymmetric bromoaminocyclizations

A BINOL-derived chiral bifunctional sulfide catalyst bearing a phenylurea moiety was applied to enantioselective bromoaminocyclization reactions of 2-allylaniline derivatives, which provide optically active 2-substituted indoline products as important motifs for biologically active compounds. A protecting group on the nitrogen of the 2-allylaniline substrate was carefully optimized, and highly enantioselective reactions were achieved by employing the p-biphenylsulfonyl-protected substrates. The origin of the good level of enantioselectivity for the present bromoaminocyclization was also investigated on the basis of DFT calculations. The resultant optically active 2-(bromomethyl)indoline products could be transformed to various 2-substituted indolines with no loss of the optical purity.

Diastereoselective Syntheses of Spiro[indoline-3,4 ‘-pyridin]-2-yl Carbamates via AgOTf/Ph3P-Catalyzed Tandem Cyclizations of Tryptamine-Ynesulfonamides

Spiro[indoline-3,4′-piperidine] is a significant structural scaffold in numerous polycyclic indole alkaloids with a variety of bioactivities. In this study, a synthetic strategy was developed to access spiro[indoline-3,4′-pyridin]-2-yl carbamate via an AgOTf/ PPh3-catalyzed tandem cyclization of tryptamine-ynesulfonamides. The unique feature of this strategy is the efficient intermolecular capturing of the in situ generated spiroindoleninium intermediates with carbamates, leading to the diastereoselective syntheses of spiro[indoline-3,4’-pyridin]-2-yl carbamate derivatives. A broad scope of this cyclization was demonstrated by a variety of tryptamine-ynesulfonamide substrates and several carbamates. A plausible mechanism of this reaction was proposed.
