"6-Alkynyl-7-benzylpurines were prepared by the Sonogashira reaction from 6-chloro-7-benzylpurines and terminal alkynes. The prepared alkynylpurines were cyclotrimerized with various 1,6-diynes in the presence of Ni(cod)2/2PPh3 catalytic system into the corresponding 6-aryl-7-benzylpurines under ambient conditions. The prepared 6-alkynyl- and 6-aryl-7-benzylpurines were tested for cytostatic activity." . "Klepet\u00E1\u0159ov\u00E1, Blanka" . . "cyclotrimerization; purine; alkyne; nickel; catalysis"@en .
