Abstract
The application of the DMSO/SOCl2 system enabled the intramolecular cyclization/chlorination of N,N-disubstituted 2-alkynylanilines, leading to the synthesis of a series of 3-chloroindoles with moderate to good yields. Differing from the previously reported interrupted Pummerer reaction featuring the introduction of SMe moiety, the current approach adopted an alternative pathway that realized the incorporation of chlorine atom to the indole skeleton via a desulfonylative chlorocyclization process.

Abstract
A new and efficient method has been developed to synthesize dispiro[oxindole/acenaphthylenone-benzofuranone]pyrrolidine compounds. This is done by triggering the 1,3-dipolar cycloaddition reaction of azomethine ylides by reacting isatin/acenaphthoquinone with L-picolinic acid/L-proline/sarcosine/L-thioproline/tetrahydroisoquinolines, in a highly regioselective manner in an ionic liquid [DBU][Ac] with 4'-chloro-auron[2-(4-chlorobenzylidene)benzofuran-3(2H)-one]. Single-crystal X-ray diffraction data support the proposed structures of the new compounds. The heterocycles derived from amino acids such as L-picolinic acid, L-proline, and L-thioproline showed significant inhibitory effects against six human solid tumors, including lung, breast, cervix, colon, and others. These new structures were also tested in the active sites of the MDM2 receptor to further study their antiproliferative effects.

Abstract
Heterocyclic fused-ring systems are of utmost importance because of their presence in many natural products with biological activity. Pyrroloindoles are tricyclic heterocycles that are present in various bioactive and medicinally valuable compounds. Herein, we report the synthesis of phenylene-bridged bis-pyrrolo[1,2-a]indole crowned macrocycles 1-3 in which the pyrrolo[1,2-a]indole moieties were formed via intramolecular fusion. The macrocycles were thoroughly characterized by 1D and 2D NMR, HRMS and X-ray crystallographic studies. The X-ray structure revealed that the two pyrrolo[1,2-a]indole moieties were parallel to each other, and one pyrrolo[1,2-a]indole unit was deviated by an angle of 9.54° while the other pyrrolo[1,2-a]indole unit was deviated by an angle of 12.0° from the mean plane defined by 28 core atoms. The macrocycles 1-3 absorb in the visible region and readily undergo oxidations because of their electron rich nature. The macrocycles 1-3 upon treatment with trifluoroacetic acid (TFA) generates the corresponding cation radicals 1-3.+ which were stable in the open air for a week. The cation radicals 1-3.+ absorb strongly in the NIR region and the experimental observations on crowned macrocycles 1-3 were corroborated by DFT and TD-DFT studies.

Abstract
AbstractThis review aims to provide a comprehensive overview of condensation-based methods for the C–H bond functionalization of amines that feature azomethine ylides as key intermediates. These transformations are typically redox-neutral and share common attributes with classic name reactions such as the Strecker, Mannich, Friedel–Crafts, Pictet–Spengler, and Kabachnik–Fields reactions, while incorporating a redox-isomerization step. This approach provides an ideal platform to rapidly transform simple starting materials into complex amines.1 Introduction1.1 General Remarks1.2 Overview1.3 Scope of This Review2 Aromatization of Cyclic Amines2.1 Pyridines from Piperidine2.2 Isoquinolines from Tetrahydroisoquinolines and Quinolines from Tetrahydroquinolines2.3 Pyrroles from 3-Pyrroline or Pyrrolidine2.4 Indoles from Indolines3 Pericyclic Reactions3.1 (3+2)-Dipolar Cycloadditions3.2 6π-Electrocyclizations3.3 1,5-Proton Shifts4 Redox-Variants of Classic Transformations Incorporating a C–H Bond Functionalization Step4.1 α-Cyanation4.2 α-Alkynylation4.3 α-Phosphonation4.4 α-Arylation4.5 α-Alkylation with Ketones4.6 Redox-Ugi Reaction4.7 Miscellaneous Intermolecular Reactions5 Redox-Annulations6 Reactions Involving β-C–H Bond Functionalization7 Outlook

Abstract
We prepared a series of free NH and N-substituted dibenzonthiazines with potential anti-tumor activity from N-aryl-benzenesulfonamides. A biological test of synthesized compounds (59 samples) was performed in vitro measuring their antiproliferative activity against a panel of six human solid tumor cell lines and its tubulin inhibitory activity. We identified 6-(phenylsulfonyl)-6H-dibenzo[c,e][1,2]thiazine 5,5-dioxide and 6-tosyl-6H-dibenzo[c,e][1,2]thiazine 5,5-dioxide as the best compounds with promising values of activity (overall range of 2-5.4 μM). Herein, we report the dibenzothiazine core as a novel building block with antiproliferative activity, targeting tubulin dynamics.

Abstract
Isoquinoline alkaloids are a large group of natural products in which 1,2,3,4-tetrahydroisoquinolines (THIQ) form an important class. THIQ based natural and synthetic compounds exert diverse biological activities against various infective pathogens and neurodegenerative disorders. Due to these reasons, the THIQ heterocyclic scaffold has garnered a lot of attention in the scientific community which has resulted in the development of novel THIQ analogs with potent biological activity. The present review provides a much-needed update on the biological potential of THIQ analogs, their structural-activity relationship (SAR), and their mechanism of action. In addition, a note on commonly used synthetic strategies for constructing the core scaffold has also been discussed.

Abstract
The use of eco-compatible synthetic procedures in organic reactions and, in particular, in 1,3-dipolar cycloaddition reactions, has recently received a great deal of attention and considerable progress has been achieved in this area in the last years. This review summarizes the approaches currently employed to synthesize heterocyclic compounds by catalyzed 1,3-dipolar cycloadditions in green solvents in the last six years. Our choice to do a selection of the literature from 2014 to 2019 was made considering the absence of a recent review about this period, to our knowledge. Several examples to construct heterocycles by 1,3-dipolar cycloadditions will be discussed in this work subdivided in function of the most important class of non-conventional and green solvents, i.e., ionic liquids (ILs), deep eutectic solvents (DES), and water.

Abstract
A facile, highly efficient, and greener method for the synthesis of new 1,4-disubstituted-1,2,3-triazoles was conducted using [Et3NH][OAc] as a medium by the implementation of ultrasound irradiation via click chemistry, affording excellent yields. The present synthetic method exhibited numerous advantages such as mild reaction conditions, excellent product yields, minimal chemical waste, operational simplicity, shorter reaction time, and a wide range of substrate scope. The synthesized compounds were further evaluated for in vitro antifungal activity against five fungal strains, and some of the compounds displayed equivalent or greater potency than the standard drug. A molecular docking study against the modelled three-dimensional structure of cytochrome P450 lanosterol 14α-demethylase was also performed to understand the binding affinity and binding interactions of the enzyme. Furthermore, the synthesized compounds were evaluated for DPPH radical scavenging activity and antitubercular activity against Mycobacterium tuberculosis H37Rv strain.

Abstract
A concise, atom-economic strategy for the synthesis of pyrrolizines with amino and keto substituents has been developed. It includes the following key steps: (i) the base-catalyzed (K3PO4/DMSO) addition of a benzylamine to 2-acylethynylpyrroles and (ii) noncatalyzed addition of enaminones obtained to the triple bond of acylacetylenes followed by intramolecular cyclization of the intermediate pentadiendiones thus formed to the target 1-(benzylamino)-2-acyl-3-methylenoacylpyrrolizines.

Abstract
In order to find novel bioactive compounds with significant antifungal activities, a series of novel 1,4-disubstituted 1,2,3-triazoles containing an indole ring via CuCl2/Zn-catalyzed Huisgen cycloaddition were designed, synthesized, and characterized. Antifungal activity against colletotrichum capsici and cotton physalospora pathogens of all the prepared compounds was evaluated, and the test results indicated that these compounds, especially 4g and 4h, showed significant inhibitory effects for fungi. All the synthesized compounds have been characterized by IR, NMR, and high-resolution mass spectra experiments. The preliminary structure activity relationship is also discussed in this paper.

Abstract
BACKGROUND Natural product-inspired synthesis is a key incorporation in modern diversity-oriented synthesis to yield biologically novel scaffold. Inspired by β-carboline fused system, we have designed molecules with multi ring fused scaffold by modifying the tricyclic pyrido[3,4- b]indole ring with imidazo[1,2- a]isoquinoline. METHODS A highly convergent approach with new C-N and C-C bond formation to synthesize multiring fused complex scaffold imidazo[1,2- a]isoquinolinies as fluorophores. N-nucleophile-induced ring transformation of 2 H-pyran-2-one followed by in situ cis-stilbene-type oxidative photocyclization yielded new C-C bond formation without additional oxidant. The cytotoxicity, effective concentrations, and the mode of action of the synthesized analogs were determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT),, plaque reduction, time of addition, and reverse transcriptase Polymerase Chain Reaction (PCR). RESULTS Novel imidazo[1,2- a]isoquinoline analogs were prepared, and the results revealed that trans isomer of cyclopropyl analog (EC50 35 and 37.5 µg/ml) and trans isomer of citric acid salt of phenyl analog (EC50 38.2 and 39.8 µg/ml) possess significant anti-Herpes Simplex Virus (HSV) activity with selectivity index of >10. The kinetic study demonstrated that both the analogs inhibited HSV-1F and HSV-2G at 2-4 h postinfection. Finally, western blot and reverse transcriptase PCR assays revealed that both the analogs suppressed viral immediate early transcription. CONCLUSION Novel imidazo[1,2- a]isoquinoline analogs were synthesized from pyranone with appropriate amines. Two compounds showed better antiviral profile on HSV-infected Vero cells, compared to the standard drug acyclovir (ACV). Overall, we discovered a promising scaffold to develop a nonnucleoside lead targeting the viral immediate early transcription for the management of HSV infections.
