PdII-Catalyzed Purine-Directed Ortho Nitration of 6-Arylpurines by C(sp2)–H Activation: A Practical Approach to Synthesize 6-(2-Nitroaryl)-Purine Derivatives

Herein we report a method for PdII-catalyzed purine-directed ortho nitration of 6-arylpurines via C(sp2)–H activation by using tBuONO/O2 as nitration agent. This procedure is highly efficient and produces a range of 6-(2-nitroaryl)-purine derivatives with good chemoselectivity and functional-group tolerance. The utility of the method is further illustrated in the synthesis of antibacterial agent.

Visible-Light-Mediated Monoselective Ortho C-H Arylation of 6-Arylpurine Nucleosides with Diazonium Salts

A combined palladium- and photoredox-catalyzed monoselective arylation of 6-arylpurine nucleosides has been developed by employing purine as a directing group via the photoredox reaction, and many functional groups are well tolerated in this direct C-H arylation condition. Various of functionalized purines (nucleosides) which are potentially of great importance in medicinal chemistry could be obtained under visible light irradiation at room temperature within 4 h.

Microwave promoted palladium-catalyzed Suzuki-Miyaura cross-coupling reactions of 6-chloropurines with sodium tetraarylborate in water

An efficient method for the synthesis of 6-arylpurines (nucleosides) was developed via Suzuki-Miyaura cross-coupling reactions of 6-chloropurines (nucleosides) and sodium tetraarylborate in neat water (ethanol). The process gave good to high isolated yiel

Synthesis and biological testing of purine derivatives as potential ATP-competitive kinase inhibitors

On the basis of ATP adenine, a series of adenine and purine derivatives was prepared and tested for their ability to inhibit a spectrum of disease-related kinases. There has been scant research investigating the potential of cosubstrate derived kinase inhibitors for other kinases than CDKs. Our inhibitor design combined the purine system from the original cosubstrate ATP and phenyl moieties in order to explore possible interactions with the different regions of the ATP binding site in several disease-related protein kinases. There have been a number of hits for the assayed substances, which led us to conclude that the spectrum of compounds may prove to be a valuable tool kit for the evaluation of bonding and selectivity patterns for a wide variety of kinases.

Iron-catalyzed cross-coupling reactions

Simple iron salts such as FeCln, Fe(acac)n (n = 2,3) or the salen complex 4 turned out to be highly efficient, cheap, toxicologically benign, and environmentally friendly precatalysts for a host of cross-coupling reactions of alkyl o

Coupling of Diazopurines, a Curious Steric Effect in a Free Radical Reaction

The reaction of adenine derivatives with nitrite esters in the presence of arenes was examined and found to give 6-arylpurines in good (83percent) to poor (11percent) yield.The arylated products consisted only of the meta and para isomers; none of the anticipated ortho isomers were found.The predominance of meta- and para-substituted products is attributed to steric effects.The evidence that the reaction proceeds via a purine radical includes light stimulation, relative insensitivity to electronic factors, and the facile reaction of the purine intermediate with pyridine N-oxide.Photolysis of 6-iodo-9-benzylpurine in the presence of anisole gave the same mixture of 6-(m-methoxyphenyl)- and 6-(p-methoxyphenyl)purine as did diazotization, suggesting that both reactions involve the same purine radical.
