Abstract:
Novel hydrogen-phosphonodithioate compositions are provided which are particularly useful for forming internucleotide and internucleoside linkages in oligonucleosides or oligonucleotides. The oligonucleotides and analogs thereof made by using the hydrogen-phosphonodithioate compositions may be therapeutically useful as antiviral and anticancer agents and may have other therapeutic or diagnostic uses. A method for making the hydrogen-phosphonodithioates is provided as well as a method for converting same to an activated intermediate for substitution on the phosphorus atom.
Abstract:
Die Erfindung betrifft neue Ester des Glyzerins, bei denen eine der OH-Gruppen des Glyzerins mit einer Phenolcarbonsäure verestert ist, während die beiden anderen OH-Gruppen mit durch langkettige Alkohole, Amine, Mercaptane oder Phenolverbindungen substituierten Phosphor- oder Phosphorigsäure verestert sind. Die Produkte dienen als Licht- und Wärmestabilisatoren für Kunststoffe. Sie zeichnen sich durch hohe Hydrolyse- und Extraktionsfestigkeit aus.

Abstract:
Verbindungen der Formel sind Phosphorylierungsreagenzien, die mit acylierbaren Wasserstoffatomen unter Abspaltung des Amins HNR 3 R 4 reagieren. Die erhaltenen Verbindungen werden zu den entsprechenden Phosphat-, Thiophosphat- oder Selenophosphatderivaten oxidiert und dann die Reste R 1 und R 2 mit Basen abgespalten. Die chemische Natur der Reste R 1 , R 2 , R 3 und R 4 richtet sich dementsprechend nach diesen Forderungen der Abspaltbarkeit.

Abstract:
Compounds of the formula ##STR1## are phosphorylating reagents which react with acylatable hydrogen atoms with elimination of the amine HNR.sup.3 R.sup.4. The resulting compounds are oxidized to give the corresponding phosphate, thiophosphate or selenophosphate derivatives, and the radicals R.sup.1 and R.sup.2 are then split off by means of bases. The chemical nature of the radicals R.sup.1, R.sup.2, R.sup.3 and R.sup.4 accordingly depends on the requirements for these cleavage reactions.
