Abstract
Cyclic oligonucleotides and analogues (cONs) are highly specific ligands for DNA, RNA and proteins. cONs are described in several diagnostic and therapeutic applications, as well as in elucidating enzyme mechanisms and as lead structures for development of new drugs because of their unusual chemical and biological properties in comparison with linear counterparts. In numerous structural studies it has been shown that conformational constraints imposed by circularity cause unique topologies, which in some cases can result into peculiar ON nanostructures. The wide field of applications of cONs has called for the definition of easy and efficient strategies to produce such compounds.
In this review, we will describe the enzymatic and chemical approaches reported for the synthesis of cONs with a particular focus on the chemical ones. We proceed following a chronological order from the earliest to the latest methods and improvements, describing at first the natural cyclic ONs and then modified linkages and cyclic analogues.

Advances of Heterocyclic Chemistry with Pesticide Activity
Global food safety and security will continue to be a global concern for the next 50 years and beyond. Plant diseases have had a significant impact on food safety and security throughout the entire food chain, from primary production to consumption. While conventional chemical pesticides have been traditionally used for ...read more
Calculation design of covalent/metal organic framework based catalysts
This research area combines theoretical computation and screening with machine learning for the design of covalent/metal organic framework-based catalysts, bridging the disciplines of organic chemistry, physical chemistry, computational chemistry, materials science, and machine learning. It covers several critical aspects: designing and synthesizing organic catalysts for improved performance, applying computational methods ...read more
Carbohydrates conversion in biofuels and bioproducts
Biomass pretreatment, hydrolysis, and saccharification of carbohydrates, and sugars bioconversion in biofuels and bioproducts within a biorefinery framework. Carbohydrates derived from woody biomass, agricultural wastes, algae, sewage sludge, or any other lignocellulosic feedstock are included in this issue. Simulation, techno-economic analysis, and life cycle analysis of a biorefinery process are ...read more
Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
