synthesis seems to be the technique of choice for the preparation of labile multifunctional compounds linked by phosphodiester bonds in solution. Thus, to make the lipophilic oxysterols water-soluble for biologicalstudies, we have prepared several combinations between polyoxygenated sterols and nucleoside analogues using Cβ-cyanoethoxy)bis(diisopropylamine) phosphine 2 as phosphorylating agent. This approach
