Abstract
A method of masking 3â²-H-phosphonate group for the solution-phase synthesis of ribonucleotide by H-phosphonate approach was described. The phosphonic acid group was masked by bis-(2-cyanoethyl) boranophosphate during the reactions. After a successive demasking treatment by triethylamine, trityl cation, and triethylamine, the triethylammonium 3â²-H-phosphonate nucleotide can be obtained efficiently ready for the coupling cycle in synthesis of oligonucleotide.
