dcterms:description
A methodology for the synthesis of (E)-6-alkenylpurines, starting from 6-iodopurines, based on a Pd-catalyzed stannation/protodestannation protocol is described. 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.
