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.

A potential material for removal of nitrogen compounds in petroleum and petrochemical derivates

Activated carbon from coconut shell (Elaeis guineensis), in both crude and chemically modified forms, was evaluated as an adsorbent for removing nitrogen compounds of samples from synthetic and real fuel. The preliminary adsorption tests showed that 97.95 of indoline was removed by sulfuric acid-treated activated carbon (SAAC). The optimum conditions toward adsorption of nitrogen-containing compounds in crude oil (54 degrees C, 150 rpm and 1.104 g of adsorbent) was evaluated according to the design of experiments (DOE) technique associated with Differential Evolution optimization algorithm and an effective removal of 30.37% of basic nitrogenous compounds present in crude oil was achieved. For comparative effect, the tests were carried out using the previously optimized condition with the vacuum residue, diesel S-500, and diesel S-10, obtaining the removal of 21.56%, 44.44%, and 62.09%, respectively. Complementing the quantitative analysis, the analysis of mass spectrometry confirmed that coconut shell is a potential material for selective adsorption of nitrogenous compounds.

Catalyst-Free Stereocontrolled Formal [3+2]-Cycloaddition of CO2 for the Synthesis of Enantiopure Spiro[indoline-3,5 ‘-oxazolidine]-2,2 ‘-diones under Aqueous and Ambient Conditions

A highly efficient regio- and stereoselective spontaneous formal [3 + 2]-cycloaddition of CO2 in aqueous medium is developed for the one-pot synthesis of spiro[indoline-3,5′-oxazolidine]-2,2’-diones with excellent enantiopuirity (ee up to 99%) under catalyst-free and ambient conditions. The detailed study reveals NH-spiroaziridine- and 3-(aminomethyl)-3-chloro-oxindoles, two in situ generated reactive intermediate compounds for the spontaneous cycloaddition with CO2, and the latter is responsible for the stereoselectivity. An unprecedented mechanism of desulfinylation is also disclosed herewith.

Lewis-acid catalyzed dehydrative [3+2] cycloaddition reaction: A facile synthetic approach to spiro-benzoindoline oxindoles

An efficient one-pot method for the construction of C-C and C-N bond has been established from activated spiro-aziridine oxindoles using different substituted 2-naphthols by employing BF3 OEt2 as a catalyst. This method features spiro-aziridine ring-opening (Friedel-Crafts type C-C bond formation) with concomitant dehydrative formal [3+2] cycloaddition leading to the formation of a complex and diverse benzoindoline fused spiro-oxindoles in moderate to good yields with wide substrate scope. Moreover, this protocol provides an avenue for the generation of a library of bioactive spiro-cyclic fused heterocyclic motifs which may prove to be of therapeutic interest. (C) 2020 Elsevier Ltd.

Recent advances in asymmetric synthesis of 2-substituted indoline derivatives

Enantiomerically pure 2-substituted indolines are an important class of nitrogen heterocycles that occur frequently in many alkaloid natural products and biologically active compounds. Consequently, the synthesis of such skeletons is of great significance. The past years have witnessed a number of remarkable advances in the development of efficient strategies to construct this class of chiral compounds. This review summarizes the recent advances in asymmetric synthesis of 2-substituted indoline derivatives. Due to the limitation of the length, this review only summarizes those works published from January of 2012 to January of 2019. Meanwhile, methods towards synthesis of fused and spirocyclic indolines will not be discussed in this review.

A quick access tool for the one-pot, chromatography-free synthesis of the diversified dihydrospiro[indeno[1,2-b]pyridine-4,3 ‘-indoline or acenaphthylene-1,4 ‘-indeno[1,2-b]pyridine spiro-analogous via sustainable microwave condition in minimal 1:1 (v/v) aqueous ethanol without any metal catalyst is demonstrated here. This permutated spiro-casing was designed as fluorescence probe at physiological pH for selective detection of Zn2+, even in the presence of other competitive ions and showed a fluorescent enhancement with 1:1 metal/ligand complex. Moreover, this spiro sensor was successfully applied as an effective intracellular Zn2+ imaging agent in the biomedical study of human hepatocellular liver carcinoma cells (HepG2) due to its cell permeability property.

Monoamine Oxidase (MAO-N) Biocatalyzed Synthesis of Indoles from Indolines Prepared via Photocatalytic Cyclization/Arylative Dearomatization

The biocatalytic aromatization of indolines into indole derivatives exploiting monoamine oxidase (MAO-N) enzymes is presented. Indoline substrates were prepared via photocatalytic cyclization of arylaniline precursors or via arylative dearomatization of unsubstituted indoles and in turn chemoselectively aromatized by the MAO-N D11 whole cell biocatalyst. Computational docking studies of the indoline substrates in the MAO-N D11 catalytic site allowed for the rationalization of the biocatalytic mechanism and experimental results of the biotransformation. This methodology represents an efficient example of biocatalytic synthesis of indole derivatives and offers a facile approach to access these aromatic heterocycles under mild reaction conditions.

In the title Spiro compound, C34H30N2O3, the central pyrrolidine ring is fused with the tetrahydroisoquinoline ring, both having distorted envelope conformations, with the flap atoms being C and N, respectively. The methoxyphenyl group is attached to the pyrrolidine ring, and is disordered over two positions, with refined occupancies of 0.638 (6):0.362 (6) angstrom. The central pyrrolidine ring is inclined relative to the tetrahydroisoquinoline group, such that the dihedral between the non-flap atoms of each ring system is 11.29 (7)degrees. The spiro-linkage creates a dihedral angle of 83.26 (5)degrees between the indolinone ring and the nonflap atoms of the pyrrolidine ring. In the crystal, molecules are linked via C-H center dot center dot center dot O hydrogen bonds. For the major disorder component, these form C(11) chains that propagate parallel to the a axis.

3 ‘,4 ‘-Dihydro-2 ‘ H-spiro[indoline-3,1 ‘-isoquinolin]-2-ones as potential anti-cancer agents: synthesis and preliminary screening

Both tetrahydroisoquinolines (THIQs) and oxindoles (OXs) display a broad range of biological activities including anti-cancer activity, and are therefore recognized as two privileged scaffolds in drug discovery. In the present study, 24 3 ‘,4 ‘-dihydro-2 ‘ H-spiro[indoline-3,1 ‘-isoquinolin]-2-ones, designed as molecular hybrids of THIQ and OX, were synthesized and screened in vitro against 59 cell lines in the NCI-60 screen. Twenty compounds displayed weak to moderate inhibition of cell proliferation; among them, three compounds displayed at least 50% inhibition of cell proliferation. The compounds appeared to target primarily renal cell cancer lines; however, leukaemia, melanoma, non-small cell lung cancer, prostate, ovarian and even breast cancer cell lines were also affected. Therefore, this class of spirooxindoles may provide useful leads in the search for new anti-cancer agents.

Subsequently, antibacterial and antifungal activities in terms of inhibition zone diameter, minimum inhibitory concentration, minimum bactericidal concentration and antioxidant activity against the DPPH free radical of the derivatives were investigated. The results revealed acceptable biological effects of the synthetic derivatives and a significant relationship between their structure and biological activity were observed.
