Abstract [en]

A synthetic pathway towards the cap-structure of 2,2,7-trimethylguanosine containing a methylene modified triphosphate bridge have been investigated. The modification to the triphosphate bridge is hoped to slow down cap degradation and give the connected  oligunucleotide an increased lifetime. This could result in an better understanding of nuclear transport of oligonucleotides and could thereby helping to develop new treatments for different diseases. The synthesis relies on a coupling reaction between the 2,2,7-trimethylguanosine 5’phosphate and 2’-O-methyladenosine with a 5’-pyrophosphate where the central oxygen has been replaced by a methylene group. The reaction pathway consists of 9 steps of which 8 steps have been successfully performed. The last step, which includes a coupling reaction, was attempted but without successful identification and isolation of the cap-structure, and will need further attention. The reaction has been performed in a milligram scale with various yields.
