Oligonucleosides with a nucleobase-including backbone: Part 4. A convergent synthesis of ethynediyl-linked adenosine tetramers

Gunji, Hiroki,Vasella, Andrea

, p. 3229 - 3245 (2000)

Deprotection of the tetramer 24, obtained by coupling the iodinated dimer 18 with the alkyne 23 gave the 8′,5-ethynediyl-linked adenosine-derived tetramer 27 (Scheme 3). As direct iodination of C(5′)-ethynylated adenosine derivatives failed, we prepared 1
