“…(14) Heterocyclic ring systems were shown to readily participate in Sonogashira-type couplings [175,306]. Some more complex examples include reaction of 5-iodoarabinosyluridine [307], 3-iodofuran [308], 6-chloro-9H-purine [309], 8-bromoadenosine [310], 2,6-bis(4-iodopyrazol-1-yl)pyridine [311], 6-chloro-3H-pyrimidin-4-one [312], bromo-oxabicyclo[3.2.1]octadienes [28], a triazolopyrazinyl bromide [172], 5-trifloxyindoles [29], 5-bromobenzofuran [183], 3-iodo-5-bromoindole and 3-iodo-5-bromo-3-indazole [182], 7-bromo-pyrido [2,3-b]pyrazine [185], 5-iodo-1,2,3-triazoles [186,313], 4,5-diiodoimidazole [314] and 4-iodo-2-bromoquinoline [315] derivatives. Sonogashira coupling of 2-iodophenols followed by cyclization to give benzofurans was reported [183].…”

“…The quantum yield was determined to be Φ = 68 % in methanol with use of quinine sulfate as the reference fluorophore (Scheme 27). [48] Also, (2-thiazolyl)purine nucleoside 169 (Scheme 43) had an emission maximum at 457 nm, characterized by two excitation maxima (295 and 364 nm) and Φ = 41 % in ethanol (excitation at 363 nm). [68] A variety of new cyclonucleosides 106 were obtained (Scheme 27).…”

“…Tobacco Mosaic Virus) primjenom reakcije CuAAC, a O'Mahony i sur. 52 su sintezom adenozinskih dimera povezanih 1,2,3-triazolnim prstenom pokazali da je reakcija CuAAC izvediva i na elektronima siromašnim heterocikličkim sustavima kao što su primjerice purini (slika 4). Oni su u reakciji 8-etiniladenozina s 2'-azidoadenozinom izolirali adenozinski dimer 8.…”
