Abstract
An efficient approach for the preparation of tetracyclic indeno[1,2-b]indoles via Rh(III)-catalyzed C-H cascade annulation between arylhydrazines and diazo indan-1,3-diones has been established. In addition, a series of indeno[1,2-b]indoles were obtained in up to 96% yield with a wide range of substrates and high functional group tolerance. Finally, the diverse transformations of the desired products demonstrate the synthetic utility and utilization of this protocol.

Abstract
The reaction between ninhydrin-malononitrile adduct [2-(1,3-dioxo-1,3-dihydro-2H-inden-2-ylidene)malononitrile] and ethyl 2-(alkylamino)-4-aryl-4-oxo-but-2-enoates (prepared from ethyl 2,4-dioxo-4-arylbutanoate and alkylamines) in the presence of Et3N in MeCN at room temperature afforded 3-alkylamino-2-aryloyl-1',3',4-trioxo-1',3'-dihydrospiro[cyclopentane-1,2'-inden]-2-ene-5,5-dicarbonitriles in 78-95% yields. Five derivatives of these NH-acidic compounds are used to intercept the reactive zwitterionic intermediates generated from dimethyl acetylenedicarboxylate and Ph3P to produce dimethyl 4,4-dicyano-6-aryloyl-1-alkyl-1',3'-dioxo-1',2,3',4-tetrahydro-1H-spiro[cyclopenta[b]pyrrole-5,2'-indene]-2,3-dicarboxylates. Radical scavenging activity of four derivatives was investigated by radical trapping of diphenylpicrylhydrazine and ferric reduction power experiments. The antibacterial activities of six derivatives were studied by disk diffusion test on Gram-positive and Gram-negative bacteria.

Abstract
The Lewis acid-promoted self-condensation of 2-indolylmethanols has been revealed. On treatment with La(OTf)3, highly substituted indeno[1,2-b]indole derivatives have been synthesized by using easily accessible 2-indolylmethanols with up to 94% yields. The utility of this method is further highlighted by evaluating the initial photophysical properties of some prepared products, indicating that the protocol may have potential applications in the construction of novel fluorescent materials.

A highly practical method for C-CN bond formation by C-N bond cleavage on enaminones leading to the efficient synthesis of β-cyano enones is developed. The reactions take place efficiently to provide (E)-β-cyano enones with only a molecular iodine catalyst. In addition, the additional employment of oxalic acid enables the selective synthesis of (Z)-β-cyano enones.

Abstract
Chemical synthesis based on Group-Assisted Purification chemistry (GAP) has been prolifically used as a powerful, greener and ecofriendly tool so far. Herein, we report hypervalent iodine (III) mediated regio- and diastereoselective aminobromination of electron-deficient olefins using group-assisted purification (GAP) method. By simply mixing the GAP auxiliary-anchored substrates with TsNH2-NBS as nitrogen/bromine sources and PhI(OAc)2 as a catalyst, a series of vicinal bromoamines with multifunctionalities were obtained in moderate to excellent yields (53-94%). The vicinal bromoamines were obtained without column chromatography and/or recrystallization simply by washing the crude mixtures with cosolvents and thus avoiding wastage of silica, solvents, time, and labor. The GAP auxiliary is recyclable and reusable.

Abstract
This paper reports an unprecedented trifunctionalization of tertiary enaminones for the synthesis phosphoryl nitriles by the reactions of enaminones with diarylphosphine oxides and trimethylsilyl cyanide (TMSCN) without the use of any metal reagent. Employing tetrabutyl ammonium hydroxide (TBAH) as the catalyst (0.2 equiv) enables discrete cyanophosphonation. On the other hand, selective proximal cyanophosphonation has been realized in the presence of acetic acid only (AcOH).

Abstract
Ninhydrins show extensive application in organic chemistry and agriculture whereas they have been poorly investigated as bioactive molecules for medicinal chemistry purposes. A series of ninhydrin derivatives was here investigated for the inhibition of human carbonic anhydrases (CAs, EC 4.2.1.1), based on earlier evidence that gem diols are able to coordinate the metal ion from the CA active site. Ninhydrins demonstrated a micromolar inhibitory action against CA I and IX (KIs in the range 0.57-68.2 μM) and up to a nanomolar efficacy against CA II and VII (KIs in the range 0.025-78.2 μM), validated isoforms as targets in several CNS-related diseases. CA IV was instead weakly or poorly inhibited. A computational protocol based on docking, MM-GBSA and metadynamics calculations was used to elucidate the putative binding mode of this type of inhibitors to CA II and CA VII. The findings of this study testify that such pharmacologically underestimated ligands may represent interesting lead compounds for the development of CA inhibitors possessing an innovative mechanism of action, i.e., mono- or bis-coordination to the zinc ion through the diol moiety.

Abstract
A fast and efficient Selectfluor-triggered fluorination/cyclization reaction of o-hydroxyarylenaminones has been successfully developed. The reaction successfully provides an expedient method for the synthesis of 3-fluoro-chromones promoted by potassium carbonate, which shows readily available starting materials and is easy to operate. In addition, a plausible mechanism of this tandem cyclization reaction was proposed where 4 H-chromen-4-one, 2-(dimethylamino)-3,3-difluorochroman-4-one, and 3,3-difluoro-2-hydroxychroman-4-one were not found to be the reactive intermediates. Moreover, these novel compounds have been obtained in moderate to good yields, and their structures have been confirmed by 1H NMR, 13C NMR, and high-resolution mass spectrometry.

Abstract
Ninhydrin (1,2,3-indanetrione hydrate) has a remarkable breadth in different fields, including organic chemistry, biochemistry, analytical chemistry and the forensic sciences. For the past several years, it has been considered an important building block in organic synthesis. Therefore, there is increasing interest in ninhydrin-based multicomponent reactions to rapidly build versatile scaffolds. Most of the works described here are simple reactions with readily available starting materials that result in complex molecular architectures. Some of the synthesized compounds exhibit interesting biological activities and constitute a new hope for anticancer agents. The present review aims to highlight the multicomponent reactions of ninhydrin towards diverse organic molecules during the period from 2014 to 2019. This article aims to review recent multicomponent reactions of ninhydrin towards diverse organic scaffolds, such as indeno-fused heterocycles, spiro-indeno heterocycles, quinoxalines, propellanes, cage-like compounds, and dispiro heterocycles.![]()

Abstract
A new cascade bicyclization of o-alkynyl aldehydes with thiazolium salts is described, in which 25 examples of densely functionalized indeno[2,1-b]pyrroles are achieved in a functional-group-compatible manner. Thiazole carbenes generated in situ from thiazolium salts play dual roles as reaction partners and as NHC catalysts. The synthetic utility of these bicyclization reactions results in subsequent C-C bond-forming events to rapidly build up molecular complexity.

Abstract
A one-pot two-step synthesis of functionalised 6,7-dihydro-1H-indol-4(5H)-ones from 1,3-cyclohexanediones, benzylamines, and 2-(2-oxo-2-phenylethylidene)-1H-indene-1,3(2H)-dione has been achieved. The advantages of this approach are operational simplicity, good yields of the products and avoidance of the use of any ligands, metal catalysts, acidic media, or column chromatography.
