ABSTRACTSupercapacitor is a newly-developed device for electrochemical energy storage with high power density, long life span, as well as rapid capture and storage of energy. Carbon-based materials, from carbon nanospheres, nanotubes and nanofibers to graphene, are the most commonly used electrode materials for supercapacitors. Our group has engaged in the research of carbon nanomaterials over the past decade. Herein we summarize some typical carbon nanomaterials and their synthetic routes based on our published works, which is expected to provide the theoretical and experimental basis for further applications on carbon-based energy storage devices.

Quinoxalines are observed in several bioactive molecules and have been widely employed in designing molecules for DSSC's, optoelectronics, and sensing applications. Therefore, developing newer synthetic routes as well as novel ways for their functionalization is apparent.

Herein, we review the recent progress in the synthesis of representative nonsteroidal anti-inflammatory drugs (NSAIDs), ibuprofen and naproxen. Although these drugs were discovered over 50 years ago, novel practical and asymmetric approaches are still being developed for their synthesis. In addition, this endeavor has enabled access to more potent and selective derivatives from the key frameworks of ibuprofen and naproxen. The development of a synthetic route to ibuprofen and naproxen over the last 10 years is summarized, including developing methodologies, finding novel synthetic routes, and applying continuous-flow chemistry.

Abstract: β-Amino-α,β-enones or β-enamino carbonyl compounds are versatile synthons intermediates for the construction of various bio-active heterocyclic compounds and have been established as multipurpose synthetic precursors in organic syntheses and in pharmaceutical developments. In this work, we will discuss the different synthetic routes to obtain β-Amino-α,β-enones or β-enamino carbonyl compounds, their reactions, and their utility in the construction of organic frameworks and heterocyclic ring systems. Structurally, β-amino-α,β-enones are attractive intermediates that syndicate the ambident behaviours of nucleophilicity and electrophilicity of enones simultaneously. β-amino-α,β-enones have been known as acceptors in both 1,2- and 1,4- additions, which make them good intermediate compounds for annulation to different heterocycles.

The present study provides an overview of the chemistry and biological importance of the cationic chalcophene derivatives (furans, thiophenes and selenophenes). The summarized literature survey includes synthetic methods, reactivity and biological activities of aryl/hetarylchalcophenes that have been reported mainly from 2001 to 2019 focusing on monochalcophenes. A discussion demonstrating the proposed mechanisms of some interesting synthetic routes and linking structure features to biological activities is presented. These classes of compounds including cationic chalcophenes possess antiproliferative, antimicrobial and antiprotozoal activities. This review highlights recent advances for arylchalcophene derivatives and may contribute to the design and structure optimization of new chalcophene derivatives in the future.

Enzymes are nature’s catalyst of choice for the highly selective and efficient coupling of carbohydrates. Enzymatic sugar coupling is a competitive technology for industrial glycosylation reactions, since chemical synthetic routes require extensive use of laborious protection group manipulations and often lack regio- and stereoselectivity. The application of Leloir glycosyltransferases has received considerable attention in recent years and offers excellent control over the reactivity and selectivity of glycosylation reactions with unprotected carbohydrates, paving the way for previously inaccessible synthetic routes. The development of nucleotide recycling cascades has allowed for the efficient production and reuse of nucleotide sugar donors in robust one-pot multi-enzyme glycosylation cascades. In this way, large glycans and glycoconjugates with complex stereochemistry can be constructed. With recent advances, LeLoir glycosyltransferases are close to being applied industrially in multi-enzyme, programmable cascade glycosylations.
