Transition metal complex catalyzed cocyclotrimerization of protected alkynylpurine ribonucleosides 1 with various diynes 2 gave rise to a series of 6-arylpurine nucleosides 3 that were further deprotected to free nucleosides 4. Generally, the best yields
Novel method for preparation of highly substituted 6-arylpurines by reactions of 6-alkynylpurines with zirconacyclopentadienes

, p. 339 - 349 (2007/10/03)
Reactions of various zirconacyclopentadienes bearing alkyl and aryl groups with 6-alkynyl-purines in the presence of NiBr2(PPh3) 2 afforded the corresponding 6-arylpurines with highly hydrophobic aryl moieties in low to mo
