✦ Synopsis
The synthesis of two backbone modified dinucleotide analogues is described in which the natural phosphodiester linkage is replaced by a 3'-5" c~xbazoyl linkage. In both cases the bridge was formed through a coupling reaction between an appropriate 3'-carbazoyl nucleoside analogue and an aldehyde nucleoside derivative. It is noteworthy that s~,ting nucleosides 4 could be common materials to obtain the 3'-carbazoyi nucleoside derivatives 2, by means of a simple, previouslydescribed chemoenzymatic procedure, and the aldehyde nucleoside 3, by an oxidation reaction.
