Detritylation of N-acyl-5′-o-tritylated deoxynucleosides, deoxynucleotides, and oligodeoxynucleotides have been quantitatively achieved in minutes at room temperature by using diethylaluminium chloride or diisobutylaluminium chloride. Reactions take place in unpolar solvents in homogeneous phase under completely aprotic conditions.

Dimer, trimer and tetramer blocks of deoxynucleoside methylphosphonodiesters d(AC), d(AT), d(ATG) and d(ATTT) were synthesizedon CPG polymer support using deoxynucleoside methylphosphonomonochloridite. Only dinucleotide methylphosphonates werephosphorylated at 5′-OH with T4-polynucleotide kinase. These phosphorylated dimers hydrolized quantitatively with NaOH (0.5 M) in 15 minutes at room temperature

Successive displacement of oxybenzotriazoyl moieties from methylphosphonicbisoxybenzotriazolide by a deoxynucleoside and a mercaptan yields the O,S-dialkyl and O-alkyl-S-arylmethylphosphonothioate diastereomers which can be resolved by flash column chromatography.

1,1,1,3,3,3-Hexafluoro-2-propy(HFP) group is a new protectinggroup for the internucleotidic bonds in the synthesis of oligodeoxyribonucleotides by the phosphoramidite method. This group can be removed rapidly by oximate treatment. Further, we have found that the phosphitylating agent, bis(diisopropylamino)-1,1,1,3,3,3-hexafluoro-2-propoxyphosphine is easy to prepare in view of their stability during
