Abstract
The first example of the synthesis of new dinucleotide cap analog containing 2('),3(')-diacetyl group on m(7)guanosine moiety is described. The desired modified cap analog, m(7,2)(')(,3)(')(-diacetyl)G[5(')]ppp[5(')]G has been obtained by the coupling reaction of triethylamine salt of m(7,2)(')(,3)(')(-diacetyl)GDP with ImGMP in presence of ZnCl2 as a catalyst in 62% yield with high purity. The structure of new cap analog has been confirmed by (1)H and (31)P NMR and mass data.
