Abstract
New applications of palladium-catalyzed Sonogashira-type cross-coupling reaction between C5-halogenated 2'-deoxycytidine-5'-monophosphate and novel cyanine dyes with a terminal alkyne group have been developed. The present methodology allows to synthesize of fluorescently labeled C5-nucleoside triphosphates with different acetylene linkers between the fluorophore and pyrimidine base in good to excellent yields under mild reaction conditions. Modified 2'-deoxycytidine-5'-triphosphates were shown to be good substrates for DNA polymerases and were incorporated into the DNA by polymerase chain reaction.

NUCLEOSIDES, NUCLEOTIDES & NUCLEIC ACIDS 2021; 41:36-44. [PMID: 34696692 DOI: 10.1080/15257770.2021.1994992] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/07/2021] [Revised: 10/13/2021] [Accepted: 10/14/2021] [Indexed: 10/20/2022]
Abstract
A simple, reliable, straightforward, and efficient method for the gram-scale chemical synthesis of purine locked nucleic acid (LNA) nucleotides such as LNA-guanosine-5'-triphosphate (LNA-GTP) and LNA-adenosine-5'-triphosphate (LNA-ATP) starting from the corresponding nucleoside is described. The overall reaction utilizes an improved "one-pot, three-step" Ludwig synthetic strategy that involves the monophosphorylation of LNA nucleoside, followed by the reaction with tributylammonium pyrophosphate and subsequent hydrolysis of the resulting cyclic intermediate using water to furnish the corresponding purine LNA nucleotide in good yield with high purity (>99.5%).

Abstract
Rolling circle amplification (RCA) is a powerful tool for the construction of DNA nanomaterials such as hydrogels, high-performance scaffolds and DNA nanoflowers (DNFs), hybrid materials formed of DNA and magnesium pyrophosphate. Such DNA nanomaterials have great potential in therapeutics, imaging, protein immobilisation, and drug delivery, yet limited chemistry is available to expand their functionality. Here, we present orthogonal strategies to produce densely modified RCA products and DNFs. We provide methods to selectively modify the DNA component and/or the protein cargo of these materials, thereby greatly expanding the range of chemical functionalities available to these systems. We have used our methodology to construct DNFs bearing multiple surface aptamers and peptides capable of binding to cancer cells that overexpress the HER2 oncobiomarker, demonstrating their potential for diagnostic and therapeutic applications.

Abstract
A facile, straightforward, reliable, and efficient chemical synthesis of inosine nucleotides such as inosine-5'-monophosphate, inosine-5'-diphosphate, and inosine-5'-triphosphate, starting from inosine is delineated. The inosine-5'-monophosphate is achieved by the highly regioselective monophosphorylation of inosine using the Yoshikawa procedure. The inosine-5'-diphosphate is obtained by the coupling reaction of tributylammonium phosphate with an activated inosine-5'-monophosphate using zinc chloride as a catalyst. The inosine-5'-triphosphate is efficiently achieved by the improved "one-pot, three-step" Ludwig synthetic strategy. In all the cases, the resulting final product is isolated in good yields with high purity (>99.5%).

Abstract
The utilization of 5-aminopropargyl nucleotide serves as a versatile molecular biology tool for the introduction of functional groups into a nucleic acid target of interest by using in-vitro enzymatic incorporation method. This article describes a simple, reliable, general, and efficient two-step chemical method for the synthesis of 5-(3-aminopropargyl)-2'-deoxycytidine-5'-O-triphosphate, 5-(3-aminopropargyl)-cytidine-5'-O-triphosphate, 5-(3-aminopropargyl)-2'-deoxyuridine-5'-O-triphosphate, and 5-(3-aminopropargyl)-uridine-5'-O-triphosphate, starting from the corresponding pyrimidine triphosphate. The first step involves regioselective C-5 iodination of pyrimidine triphosphate using N-iodosuccinimide and sodium azide. In the second step, propargylamine is coupled to the iodo-pyrimidine using the palladium-catalyzed Sonogashira reaction, producing good yields of highly pure (>99.5% HPLC) 5-aminopropargyl-pyrimidine-5'-O-triphosphate. In this approach, the palladium-catalyzed Sonogashira coupling reaction is highly chemoselective and does not involve protection and deprotection. © 2019 by John Wiley & Sons, Inc.

Abstract
Propargylamines are a versatile class of compounds which find broad application in many fields of chemistry. This review aims to describe the different strategies developed so far for the synthesis of propargylamines and their derivatives as well as to highlight their reactivity and use as building blocks in the synthesis of chemically relevant organic compounds. In the first part of the review, the different synthetic approaches to synthesize propargylamines, such as A3 couplings and C-H functionalization of alkynes, have been described and organized on the basis of the catalysts employed in the syntheses. Both racemic and enantioselective approaches have been reported. In the second part, an overview of the transformations of propargylamines into heterocyclic compounds such as pyrroles, pyridines, thiazoles, and oxazoles, as well as other relevant organic derivatives, is presented.
