title: A novel class of condensing reagents in phosphodiester oligodeoxyribonucleotides synthesis. Application of the constituents of free terminal carboxy oxytocine gene.
abstract: Benzotriazol-1-yl-oxy-tris (dimethylamino) phosphonium salts have been used as novel condensing agents to promote internucleotide bond formation in phosphotriester oligodeoxyribonucleotide synthesis. The effectiveness of these stable compounds has been shown by the synthesis of the six oligodeoxyribonucleotide building blocks of the carboxy terminal oxytocine gene. Some modifications incorporated in the phosphotriester method include a rapid procedure to prepare the fully protected dideoxyribonucleotide blocks and size exclusion chromatography of the deprotected oligodeoxyribonucleotides. The triester oligodeoxyribonucleotides were studied by chemical ionization mass spectrometry.
