Deoxynucleoside phosphoramidites can be prepared in good yield from deoxynucleosides, bis- dialkylaminophosphines , and the corresponding dialkylamine hydrotetrazolide or tetrazole as catalysts. These phosphoramidites generated in situ lead to the direct synthesis of deoxyoligonucleotides on polymer supports.

A family of new anionic nucleotide based lipids featuring thymidine-3'-monophosphate as nucleotide and 1,2-diacyl-sn-glycerol as lipid moiety for in vitro delivery of nucleic acids is described. The nucleotide lipids were prepared in three steps starting from 1,2-diacyl-sn-glycerols and 2'-deoxythymidine-3'-phosphoramidite. Gel

High-performance oxygen reduction reaction (ORR) catalysts based on metal-free nitrogen-containing precursors and carbon nanotubes are reported. The investigated systems allow the evaluation of the effect of nitrogen-containing groups towards ORR and the results show that the catalysts are compatible with
