This review gives a short account of selected aspects of oligoribonucleotide synthesis via the H-phosphonate method. It includes: (i) recent methods for the preparation of suitably protected ribonucleoside 3'-H-phosphonates (the phosphonylation step), (ii) some chemical and stereochemical features of the formation of H-phosphonate internucleosidic linkages, and (iii) stereoselective synthesis of oligoribonucleoside phosphorothioates using chemo-enzymatic approach.

UI	MeSH Term	Description	Entries
D009696	Nucleic Acids	High molecular weight polymers containing a mixture of purine and pyrimidine nucleotides chained together by ribose or deoxyribose linkages.	Nucleic Acid,Acid, Nucleic,Acids, Nucleic
D009841	Oligonucleotides	Polymers made up of a few (2-20) nucleotides. In molecular genetics, they refer to a short sequence synthesized to match a region where a mutation is known to occur, and then used as a probe (OLIGONUCLEOTIDE PROBES). (Dorland, 28th ed)	Oligonucleotide
D010712	Phosphatidic Acids	Fatty acid derivatives of glycerophosphates. They are composed of glycerol bound in ester linkage with 1 mole of phosphoric acid at the terminal 3-hydroxyl group and with 2 moles of fatty acids at the other two hydroxyl groups.	Ammonium Phosphatidate,Diacylglycerophosphates,Phosphatidic Acid,Acid, Phosphatidic,Acids, Phosphatidic,Phosphatidate, Ammonium
D011725	Pyridines	Compounds with a six membered aromatic ring containing NITROGEN. The saturated version is PIPERIDINES.
D011743	Pyrimidines	A family of 6-membered heterocyclic compounds occurring in nature in a wide variety of forms. They include several nucleic acid constituents (CYTOSINE; THYMINE; and URACIL) and form the basic structure of the barbiturates.
