The synthesis of novel fluorescent N (9)-alkylated 2-amino-6-triazolylpurine and 7-
deazapurine derivatives is described. A new C (2)-regioselectivity in the nucleophilic …

The Cu (I)-or Ag (I)-catalyzed cycloaddition between 8-ethynyladenine or guanine
nucleosides and TMSN3 gave 8-(1-H-1, 2, 3-triazol-4-yl) nucleosides in good yields. On the …

Purines, which are heterocyclic compounds built up of fused pyrimidine and imidazole rings,
serve as ubiquitous structural cores of nucleic acids (DNA and RNA), natural products, bio …

Silver-catalyzed direct lactonization of 1, 4-disubstituted 1, 2, 3-triazole acids through C (5)–
H acyloxylation is reported. This method provides a concise and efficient pathway to …

We developed and presented here a ferrocene-catalyzed C–H imidation of 7-deazapurines
(pyrrolo [2, 3-d] pyrimidines) with N-imidyl peroxyesters. The reactions occur regioselectively …

A simple and efficient synthesis of isomeric 7-deazapurine–1, 2, 3-triazole conjugates with
amino substituents from readily available 9-alkyl-2, 6-diazido-7-deazapurines has been …

The chapter describes the functionalization of pyrimidine and purine nucleosides by direct C–
H bond activation in nucleobases. The chapter is organized by the position of the C–H bond …

An efficient palladium-catalyzed selective decarboxylation/C–H activation coupling of aryl
acid with thiazole and oxazole under the assistance of 1, 2, 3-triazole ring were developed …

In the present paper, we report an expedient total synthesis of triciribine, a tricyclic 7-
deazapurine nucleoside and protein kinase B (AKT) inhibitor, in 35% overall yield. Our …

This chapter addresses recent advances in selective functionalization of the quinazoline
core, which is present in various pharmacologically important molecules and in molecules …
