The alkynylation reactions were catalyzed by Pd(OAc)2/PPh3 in acetonitrile. The Pd-catalyzed stannation itself provided a mixture of Z-regioisomers but following protodestannation using TFA induces Z to E isomerisation giving (E)-6-alkenylpurines. The reactivity of other 2- and 6-alkynyl purines has been also studied." . . . . . "Tobrman, Tom\u00E1\u0161" .
