Abstract
A simple, reliable, and efficient method for the gram-scale chemical synthesis of pyrimidine nucleosides functionalized with C5-carboxyl, nitrile, ester, amide, or amidine, starting from unprotected uridine and cytidine, is described. The protocol involves the synthesis of 5-trifluoromethyluridine and 5-trifluoromethylcytidine with Langlois reagent (CF3 SO2 Na) in the presence of tert-butyl hydroperoxide and subsequent transformation of the CF3 group to the C5-C 'carbon substituents' under alkaline conditions. © 2024 Wiley Periodicals LLC. Basic Protocol 1: Synthesis and characterization of 5-trifluoromethyluridine (5-CF3 U) and 5-trifluoromethylcytidine (5-CF3 C) Basic Protocol 2: Conversion of 5-CF3 U and 5-CF3 C to several C5-substituted ribonucleosides.

Abstract
C5-substituted pyrimidine nucleosides are an important class of molecules that have practical use as biological probes and pharmaceuticals. Herein we report an operationally simple protocol for C5-functionalization of uridine and cytidine via transformation of underexploited 5-trifluoromethyluridine or 5-trifluoromethylcytidine, respectively. The unique reactivity of the CF3 group in the aromatic ring allowed the direct incorporation of several distinct C5-C "carbon substituents": carboxyl, nitrile, ester, amide, and amidine.

Abstract
Fluorinated nucleosides and oligonucleotides are of specific interest as probes for studying nucleic acids interaction, structures, biological transformations, and its biomedical applications. Among various modifications of oligonucleotides, fluorination of preformed nucleoside and/or nucleotides have recently gained attention owing to the unique properties of fluorine atoms imparting medicinal properties with respect to the small size, electronegativity, lipophilicity, and ability for stereochemical control. This review deals with synthetic protocols for selective fluorination either at sugar or base moiety in a preformed nucleosides, nucleotides and nucleic acids using specific fluorinating reagents.

Abstract
Cyclic adenosine diphosphate ribose (cADPR) is a second messenger involved in the Ca2+ homeostasis. Its chemical instability prompted researchers to tune point by point its structure, obtaining stable analogues featuring interesting biological properties. One of the most challenging derivatives is the cyclic inosine diphosphate ribose (cIDPR), in which the hypoxanthine isosterically replaces the adenine. As our research focuses on the synthesis of N1 substituted inosines, in the last few years we have produced new flexible cIDPR analogues, where the northern ribose has been replaced by alkyl chains. Interestingly, some of them mobilized Ca2+ ions in PC12 cells. To extend our SAR studies, herein we report on the synthesis of a new stable cIDPR derivative which contains the 2″S,3″R dihydroxypentyl chain instead of the northern ribose. Interestingly, the new cyclic derivative and its open precursor induced an increase in intracellular calcium concentration ([Ca2+]i) with the same efficacy of the endogenous cADPR in rat primary cortical neurons.

Abstract
The protocols presented in this article describe highly detailed synthesis of trifluoromethylated purine nucleotides and nucleosides (G and A). The procedure involves trifluoromethylation of properly protected (acetylated) nucleosides, followed by deprotection leading to key CF3 -containing nucleosides. This gives synthetic access to 8-CF3 -substituted guanosine derivatives and three adenosine derivatives (8-CF3 , 2-CF3 , and 2,8-diCF3 ). In further steps, phosphorylation and phosphate elongation (for selected examples) result in respective trifluoromethylated nucleoside mono-, di-, and triphosphates. Support protocols are included for compound handling, purification procedures, analytical sample preparation, and analytical techniques used throughout the performance of the basic protocols. © 2020 Wiley Periodicals LLC.

Abstract
Peptides and their synthetic analogs are a class of molecules with enormous relevance as therapeutics for their ability to interact with biomacromolecules like nucleic acids and proteins, potentially interfering with biological pathways often involved in the onset and progression of pathologies of high social impact. Nucleobase-bearing peptides (nucleopeptides) and pseudopeptides (PNAs) offer further interesting possibilities related to their nucleobase-decorated nature for diagnostic and therapeutic applications, thanks to their reported ability to target complementary DNA and RNA strands. In addition, these chimeric compounds are endowed with intriguing self-assembling properties, which are at the heart of their investigation as self-replicating materials in prebiotic chemistry, as well as their application as constituents of innovative drug delivery systems and, more generally, as novel nanomaterials to be employed in biomedicine. Herein we describe the properties of nucleopeptides, PNAs and related supramolecular systems, and summarize some of the most relevant applications of these systems.

Abstract
This review summarizes the state of knowledge on the chemical methods of C(5)-modifications of uridine and cytidine derivatives and may serve as a useful tool for synthetic chemists to choose an appropriate reaction protocol. The synthesis of 5-substituted uracil derivatives is gaining an increasing interest because of their possible applications in medicine and pharmacy. Modifications at the C(5) position of pyrimidine nucleosides can enhance their biostability, bioavailability or(and) biological activity. Among the C(5)-modified nucleosides, 5-halopyrimidines exhibit anticancer, antiviral, radio- and photosensitizing properties. Besides 5-halo-substituted derivatives, there are other examples of nucleosides with confirmed biological activity containing a C–C bond at the C(5) position in the pyrimidine ring. In recent decades, scientists have achieved great progress in the field of cross-coupling reactions. Among them, nickel-catalyzed processes provide a broad spectrum of synthetic methods that are based on less toxic and cheaper starting materials. This review summarizes the synthetic approaches based on the coupling or halogenation reactions, which enable 5-substituted pyrimidine nucleosides to be obtained. Moreover, the importance of the systems considered for medicine and pharmacy is briefly discussed.
The bibliography includes 197 references.

Abstract
This unit describes postsynthetic modification of oligonucleotides (ONs) containing 2'-deoxy-5-trifluoromethyluridine and 2'-deoxy-5-trifluoromethylcytidine. In ONs, the trifluoromethyl group at the C5 position of pyrimidine bases is converted into a variety of carboxylic acid equivalents using alkaline and amine solutions. In addition, treating fully protected and controlled pore glass (CPG)-attached ONs with methylamine and sodium hydroxide aqueous solution results in deprotection of all protecting groups (except the 4,4'-dimethoxytrityl group), cleavage from CPG, and simultaneous conversion of the trifluoromethyl group to afford the corresponding ONs containing 5-substituted pyrimidine bases. © 2019 by John Wiley & Sons, Inc.

Abstract
Protected guanosine and adenosine ribonucleosides and guanine nucleotides are readily functionalized with CF3 substituents within the nucleobase. Protected guanosine is trifluoromethylated at the C8 position under radical-generating conditions in up to 95% yield and guanosine 5'-oligophosphates in up to 35% yield. In the case of adenosine, the selectivity of trifluoromethylation depends heavily on the functional group protection strategy and leads to a set of CF3-modified nucleosides with different substitution patterns (C8, C2, or both) in up to 37% yield. Further transformations based on phosphorimidazolide chemistry afford various CF3-substituted mono- and dinucleoside oligophosphates in good yields. The utility of the trifluoromethylated nucleotides as probes for 19F NMR-based real-time enzymatic reaction monitoring is demonstrated with three different human nucleotide hydrolases (Fhit, DcpS, and cNIIIB). Substrate and product(s) resonances were sufficiently separated to enable effective tracking of each enzymatic activity of interest.

Abstract
Fluoroalkylated enaminones, such as trifluridine and 5-trifluoromethyluracil, have widespread applications in pharmaceuticals and agrochemicals. Although these kinds of pharmaceutical agent often bear CF3 and perfluoroalkyl motifs in the core structure, access to such analogues typically requires multi-step synthesis. Here, we report a mild, metal-free and operationally simple strategy for the direct perfluoroalkylation of uracils, cytosines and pyridinones through a visible-light induced pathway from perfluoroalkyl iodides. This photochemical transformation features synthetic simplicity, mild reaction conditions without any photoredox catalyst, and high functional group tolerance, providing a facile route for applications in medicinal chemistry.

Abstract
We herein present a flexible approach for the incorporation of CF3 units into a predefined site of electron-rich alkenes that exploits the regiocontrolled introduction of an iodine handle and subsequent trifluoromethylation of the C(sp2)-I bond using fluoroform-derived "ligandless" CuCF3. The broad substrate scope and functional group tolerance together with the scalability and purity of the resulting products enabled the controlled, late-stage synthesis of single regioisomers of complex CF3-scaffolds, such as sugars, nucleosides (antivirals), and heterocycles (indoles and chromones), with potential for academic and industrial applications.

Abstract
Sodium trifluoromethanesulfinate, CF3SO2Na, and trifluoromethanesulfonyl chloride, CF3SO2Cl, are two popular reagents that are widely used for the direct trifluoromethylation of a large range of substrates. Further, these two reagents are employed for the direct trifluoromethylsulfenylation and trifluoromethylsulfinylation, the introduction of the SCF3 and the S(O)CF3 group, respectively. In addition to the aforementioned reactions, the versatility of these two reagents is presented in other reactions such as sulfonylation and chlorination. This first part is dedicated to sodium trifluoromethanesulfinate.

Abstract
A facile synthesis of 2'-deoxy-5-trifluoromethyluridine and 2'-deoxy-5-trifluoromethylcytidine phosphoramidites from commercially available 2'-deoxyuridine and 2'-deoxycytidine was achieved, respectively. The obtained phosphoramidites were incorporated into oligonucleotides, and their binding affinity to double-stranded DNA (dsDNA) and single-stranded RNA (ssRNA) was evaluated by UV-melting experiments. The triplex-forming abilities of oligonucleotides including 5-trifluoromethylpyrimidine nucleobases with dsDNA were decreased. Especially, the stability of the triplex containing a trifluoromethylcytosine (CF3C)-GC base triplet was low, likely due to the low pKa of protonated CF3C by the electron-withdrawing trifluoromethyl group. A slight decrease in stability of the duplex formed with ssRNA by oligonucleotides including 5-trifluoromethylpyrimidine nucleobases was only observed, suggesting that they might be applicable to various ssRNA-targeted technologies using features of fluorine atoms.

Abstract
A convenient method for the regioselective synthesis of unsaturated nucleoside analogs in water under microwave irradiation was developed. All pyrimidine and purine nucleoside derivatives were exclusively alkylated at N1 and N9 respectively in good to excellent yields. In addition, this system could tolerate a broad range of functional groups, such as chloro, bromo, iodo, alkyl, amino, and hydroxyl groups. More importantly, the reaction scale could be enlarged to 50 mmol which made this route attractive for industrial application.
