Abstract
A novel asymmetric (4 + 3) cycloaddition of indole-2,3-quinodimethanes in situ generated from 3-methyl-2-indolylmethanols with 3-indolylmethanols via chiral phosphoric acid catalysis has been established. The cycloaddition reaction exhibits a broad substrate scope affording the diverse enantioenriched cyclohepta fused diindoles in high yields with good enantioselectivities. Significantly, this work represents the first application of 3-methyl-2-indolylmethanols as 4C synthons instead of the commonly reported three-atom synthons in cycloaddition reactions.

Abstract
An organocatalytic, highly enantioselective [6 + 2]-cycloaddition of 2-methide-2H-pyrroles with aryl acetaldehydes represents a novel and straightforward route toward densely substituted 2,3-dihydro-1H-pyrrolizin-3-ols, which were generated with good yields and high enantio- and diastereoselectivity. This one-step process involves a BINOL-phosphoric acid catalyzed reaction of 1H-pyrrole-2-carbinols with aryl acetaldehydes via the corresponding hydrogen-bonded, chiral 2-methide-2H-pyrroles.

Abstract
Catalytic asymmetric construction of chiral indole-fused rings has become an important issue in the chemical community because of the significance of such scaffolds. In this work, we have accomplished the first catalytic asymmetric (4+2) and (4+3) cycloadditions of 2,3-indolyldimethanols by using indoles and 2-naphthols as suitable reaction partners under the catalysis of chiral phosphoric acids, constructing enantioenriched indole-fused six-membered and seven-membered rings in high yields with excellent enantioselectivities. In addition, this approach is used to realize the first enantioselective construction of challenging tetrahydroindolocarbazole scaffolds, which are found to show promising anticancer activity. More importantly, theoretical calculations of the reaction pathways and activation mode offer an in-depth understanding of this class of indolylmethanols. This work not only settles the challenges in realizing catalytic asymmetric cycloadditions of indolyldimethanols but also provides a powerful strategy for the construction of enantioenriched indole-fused rings.

Abstract
An ultrasound-assisted green protocol for one-pot synthesis of a new series of pharmaceutically relevant pyrazolo quinoline derivatives (4a-t) were synthesized, characterized, and evaluated using DFT and biological activities. Pyrazolo quinoline derivatives (4a-t) were synthesized via a three-component tandem reaction of 1,3-dicarbonyl compound (1a-b), substituted aromatic aldehyde (2a-o), and 5-amino indazole (3a) in the presence of 1-butyl-3-methylimidazolium tetrafluoroborate [BMIM]BF4 ionic liquid in ethanol at ambient conditions. The main purpose of the present work is selective functionalization of pyrazolo quinoline (4a-t) core excluding another potential parallel reaction under environmentally benign reaction conditions. The present protocol shows features such as amphiphilic behavior of ionic liquid during reaction transformation, and reusability of the [BMIM]BF4 ionic liquid under mild reaction condition. All newly derived compounds were evaluated for their in vitro anti-inflammatory and antioxidant activity. Among them, compound 4c showed encouraging antioxidant activity compared with standard antioxidant ascorbic acid, and compounds 4n and 4r displayed very good anti-inflammatory activity compared with a standard drug. In this study, a theoretical computational density functional study was also executed to perform the geometry optimizations, frontier molecular orbital approach, and molecular electrostatic potential (MESP). The DFT study was carried out with the basis set DFT/B3LYP/6-31+G (d, p) level of theory. The quantum chemical descriptors (QCDS) and MESP diagrams were plotted to examine the biological reactivities of representative pyrazolo quinolines (4a-t).

Abstract
AbstractThis review summarizes recent developments in the area of Brønsted acid catalyzed, enantioselective cycloadditions of ortho-quinone methides, ortho-quinone methide imines as well as heterocyclic indole- and pyrrole-based methides. In a straightforward and single-step transformation complex polycyclic N- and O-heterocyclic scaffolds are accessible, with typically good yields and excellent stereocontrol, from simple benzyl and heterobenzyl alcohols upon acid-catalyzed dehydration. The transient precursors are hydrogen-bonded to a chiral Brønsted acid which controls the enantioselectivity of the process.1 Introduction2 Cycloadditions of ortho-Quinone Methides2.1 Brønsted Acid Catalyzed Processes2.2 Cooperative Brønsted Acid/Transition-Metal-Catalyzed Processes3 Cycloadditions of ortho-Quinone Methide Imines4 Cycloadditions of Indolyl-3-methides5 Cycloadditions of Indolyl-2-methides5.1 Brønsted Acid Catalyzed Processes5.2 Cooperative Brønsted Acid/Transition-Metal-Catalyzed Processes6 Cycloadditions of Pyrrolyl-2-methides7 Cycloadditions of Pyrrolyl-3-methides8 Conclusions

Abstract
The first Brønsted acid-catalyzed oxa-Michael reaction cascade of 2-indolylmethanols with trione alkenes was accomplished. By using this practical approach, a variety of tetracyclic indoles were readily created in an ordered sequence with excellent regio- and diastereoselectivity. 2-Indolylmethanols commendably served as four-atom synthons, as opposed to the common three-atom synthons in the previous literature reports. The regioselectivity issue was well handled by the employment of a strong Brønsted acid catalyst. In addition, its dual role in activation of substrates via hydrogen-bonding interaction and acceleration of subsequent intramolecular cyclization and dehydration was proposed to account for the high reaction efficiency.

Abstract
Catalytic asymmetric dearomatization (CADA) is a powerful tool for the rapid construction of diverse chiral cyclic molecules from cheap and easily available arenes. This work reports an organocatalytic enantioselective dearomatization of substituted thiophenes in the context of a rare remote asymmetric 1,10-conjugate addition. By suitable stabilization of the thiophenyl carbocation with an indole motif in the form of indole imine methide, excellent remote chemo-, regio-, and stereocontrol in the nucleophilic addition can be achieved with chiral phosphoric acid catalysis under mild conditions. This protocol can be successfully extended to the asymmetric dearomatization of other heteroarenes including selenophenes and furans. Control experiments and DFT calculations demonstrate a possible pathway in which hydrogen bonding plays an important role in selectivity control.

A formal [3 + 3] cyclization reaction of diaziridines and quinones has been developed offering 1,3,4-oxadiazinanes in generally high yields (up to 96%). The reaction was catalyzed by Sc(OTf)3 with a large substrate scope for both diaziridines and quinones. The synergistic activation of 1,3-dipolar diaziridines and the dipolar quinones was found to be essential to enable this reaction.

Abstract
An unprecedented iridium-catalyzed asymmetric [4 + 3] cycloaddition of racemic 4-indolyl allylic alcohols with azomethine ylides is reported. The ability of acid promoter zinc triflate to perform multiple roles is the key factor for the success of this strategy. This method provides scalable and efficient access to biologically important azepino[3,4,5-cd] indoles in good yields with generally excellent diastereo- and enantioselectivities (up to >20:1 dr and >99% ee). Mild reaction conditions, easily accessible substrates and chiral catalyst, and broad substrate scope highlight the practicality of this methodology.

Abstract
A versatile and substrate oriented multicomponent reaction for the syntheses of novel highly diastereoselective tetrahydro-1'H-spiro[pyrazolo[4,3-f]quinoline-8,5'-pyrimidine]-2',4',6'(3'H)-triones (d.r. up to 20 : 1 (syn : anti)) and tetrahydro-8H-pyrazolo[4,3-f]pyrimido[4,5-b]quinoline-8,10(9H)-diones via formation of selective multiple C-C bonds under identical reaction conditions (viz. ethanol as a reaction medium and deep eutectic mixture as a catalyst) is demonstrated. Both approaches involve mild reaction conditions, use of non-hazardous solvents, and facilitate good to excellent reaction yields of the target compounds.

Abstract
A highly efficient and straightforward synthesis of N-fused heterocyclic compounds including N'-(1-(4-nitrophenyl)ethylidene)imidazo[1,2-a]pyridine-6-carbohydrazide and N'-(1-(4-nitrophenyl)ethylidene)pyrido[1,2-a]pyrimidine-7-carbohydrazide derivatives is successfully achieved via a five-component cascade reaction utilizing cyanoacetohydrazide, 4-nitroacetophenone, 1,1-bis(methylthio)-2-nitroethylene and various diamines in a mixture of water and ethanol. The new efficient domino protocol involving a sequence of N,N-acetal formation, Knoevenagel condensation, Michael reaction, imine-enamine tautomerization and N-cyclization as key steps. The merit of this catalyst free approach is highlighted by its easily available starting materials, operational simplicity, clean reaction profile, the use of environmentally benign solvents and tolerance of a wide variety of functional groups.

Abstract
A facile, swift and ecofriendly microwave-assisted multi-component/one-pot protocol is designed for the synthesis of novel pyrazolo-[3,4-b]-quinolines at ambient temperature in aqueous ethanol as a reaction medium. The 18 novel pyrazolo-[3,4-b]-quinoline derivatives were synthesized by fusion of chosen aryl aldehyde, dimedone and 5-amino-3-methyl-1-phenylpyrazole in excellent yields (91–98%). All the molecular structures were confirmed by 1H-NMR, 15N-NMR, 13C-NMR, and HRMS data analysis. Operational simplicity, easy handling, one-step simple workup procedure, mild reaction conditions, short reaction time (≤10 min), high selectivity and no by-product formation are the striking features of the protocol. A facile, swift and ecofriendly microwave-assisted multi-component/one-pot protocol is designed for the synthesis of novel pyrazolo-[3,4-b]-quinolines at ambient temperature in aqueous ethanol as a reaction medium.![]()
