L-ribonucleosides from L-xylose

Tetrahedron, 1999
Abstract L-Xylose was converted into a L-ribose derivative via an oxidation/reduction procedure. The L-ribosyl donor was submitted to a glycosidation reaction according to Vorbruggen's conditions to give L-ribonucleosides (L-uridine, L-cytidine, L-adenosine and L-guanosine) in high yield.

2'-C-branched ribonucleosides. 2. Synthesis of 2'-C-beta-trifluoromethyl pyrimidine ribonucleosides.

Organic letters, 2001
[structure: see text]. The first synthesis of 2'-C-beta-trifluoromethyl pyrimidine ribonucleosides is described. 1,2,3,5-Tetra-O-benzoyl-2-C-beta-trifluoromethyl-alpha-D-ribofuranose (3) is prepared from 1,3,5-tri-O-benzoyl-alpha-D-ribofuranose (1) in three steps and converted to 3,5-di-O-benzoyl-2-C-beta-trifluoromethyl-alpha-D-1-ribofuranosyl bromide

[116] Mammalian pyridine ribonucleoside phosphokinase

1971
Publisher Summary Enzyme activity may be assayed by measuring the formation of nicotinate ribonucleotide with nicotinate-7- 14 C ribonucleoside and adenosine triphosphate (ATP) as substrates. The radioactive ribonucleotide produced is isolated by a small Dowex 50 column and is determined using a Geiger-Muller gas-flow counter. This chapter focuses on
