Abstract
The discovery of nalidixic acid is one pinnacle in medicinal chemistry, which opened a new area of research that has led to the discovery of several life-saving antimicrobial agents (generally referred to as fluoroquinolones) for over decades. Although fluoroquinolones are frequently encountered in the literature, the utility of quinolone compounds extends far beyond the applications of fluoroquinolones. Quinolone-based compounds have been reported for activity against malaria, tuberculosis, fungal and helminth infections, etc. Hence, the quinolone scaffold is of great interest to several researchers in diverse disciplines. This article highlights the versatility of the quinolone pharmacophore as a therapeutic agent beyond the fluoroquinolone profile.

Abstract
A highly enantioselective Pd/Xiang-Phos-catalyzed carbohetero-functionalization of norbornene is described, giving a direct access to various chiral norbornane-fused dihydrofurans and dihydro-pyrroles. This synthetic methodology provides the first example of asymmetric carboetherification of norbornene, and also tolerates norbornadiene well.

Abstract
BACKGROUND A wide variety of biological activities are exhibited by N, O and S containing heterocycles and recently, many reports appeared for the synthesis of these heterocycles. The synthesis of heterocycles with the help of metal and non-metal catalyst has become a highly rewarding and important method in organic synthesis. This review article concentrated on the synthesis of S-heterocylces in the presence of metal and non-metal catalyst. The synthesis of five-membered S-heterocycles is described here. OBJECTIVE There is a need for the development of rapid, efficient and versatile strategy for the synthesis of heterocyclic rings. Metal, non-metal and organocatalysis involving methods have gained prominence because traditional conditions have disadvantages such as long reaction times, harsh conditions and limited substrate scope. CONCLUSION The metal-, non-metal-, and organocatalyst assisted organic synthesis is a highly dynamic research field. For ßthe chemoselective and efficient synthesis of heterocyclic molecules, this protocol has emerged as a powerful route. Various methodologies in the past few years have been pointed out to pursue more sustainable, efficient and environmentally benign procedures and products. Among these processes, the development of new protocols (catalysis), which avoided the use of toxic reagents, are the focus of intense research.

Abstract
:The reactions involving the formation of C-O bond using metal as a catalyst have emerged to be one of the most influential reactions for the synthesis of heterocycles in modern organic chemistry. Catalysis by metals offers diverse opportunities to invent new organic reactions with a promising range of selectivities such as chemoselectivity, regioselectivity, diastereoselectivity, and enantioselectivity. The methodologies used earlier for synthesis were less approachable to the organic chemist because of their high cost, highly specified instrumentation and inconvenient methods. For both stereoselective and regioselective formation of five-membered O-containing heterocycles, cyclic reactions that are metal and non-metal-catalyzed have known to be very efficient. The present review article covers the applications of metal and non-metal as a catalyst for the synthesis of five-membered O-containing heterocycles.

Abstract
Some transformations are not possible with ground-state reactions even in the presence of a
catalyst, hence they are performed under photochemical conditions. Electron transfer occurs even with
the photochemical excitement of one molecule where redox reaction is not possible at the ground
state. The side products are obtained from ground-state reactions. For C-C bond formation during photochemical
reactions, there is no requirement of any chemical activation of the substrates. Therefore,
these reactions are presented here for the synthesis of fused five-membered O-heterocycles in the context
of sustainable processes from 1964 to 2019.

Abstract
The field of heterocyclic chemistry has been revolutionized using transition
metal catalysts in recent years. Various research groups have focused on the development
of general protocols to achieve better functional group compatibilities and greater levels of
molecular complexity under mild reaction conditions, using easily available starting substrates.
The methodologies used earlier for their synthesis were less approachable to organic
chemists because of their high cost, highly specified instrumentation and inconvenient
methods. For both stereoselective and regioselective synthesis of five-membered nitrogen-
containing heterocycles, cyclic reactions that are Ru-catalyzed have known to be
very efficient. These methods have many advantages as compared to alternative pathways
involved in the synthesis of heterocyclic compounds. In this review article, we concentrated
on the synthesis of nitrogen-containing five-membered heterocycles in the presence of a ruthenium catalyst.
This review mostly covers the literature published during the period from 1977-2019.

Abstract
Due to special properties of ILs (Ionic Liquids) like their wide liquid range, good solvating ability, negligible vapour pressure, non-inflammability, environment friendly medium, high thermal stability, easy recycling and rate promoters etc. they are used in organic synthesis. The investigation for the replacement of organic solvents in organic synthesis is a growing area of interest due to increasing environmental issues. Therefore, ionic liquids have attracted the attention of chemists and act as a catalyst and reaction medium in organic reaction with high activity. There is no doubt that ionic liquids have become a major subject of study for modern chemistry. In comparison to traditional processes the use of ionic liquids resulted in improved, complimentary or alternative selectivities in organic synthesis. The present manuscript reported the synthesis of multiple nitrogen containing five-membered heterocyclic compounds using ionic liquids. This review covered interesting discoveries in the past few years.

Abstract
Ultrasonic irradiation is employed to accelerate organic reactions. Under sonication reduced time, good selectivity, excellent yield, and milder conditions were observed for many organic reactions. Ultrasonic reactions are increasingly used as green, clean, and environment-friendly methods in organic synthesis in terms of energy conservation and waste minimization. The use of ultrasound irradiation is increasing in coming years. The use of ultrasound irradiation in the synthesis of five-membered N-heterocycles is depicted in the present review article.

They have been the subject of several major reviews and books, dealing with different applications and aspects of their behavior. Highly efficient methods are explored for the preparation of six-membered two nitrogen-containing heterocycles with the application of IL as a catalyst and reaction medium from 1893 to 2018.
