SYNTHESIS; MOLECULAR CONFORMATION AND BIOLOGICAL ACTIVITY OF 6-AMINO-5-AZACYTIDINE

Reaction of N-ethoxycarbonylguanidine II with 2,3,5-tri-O-benzoyl-β-D-ribosyl isocyanate (II) afforded N-ethoxycarbonylamidinourea IV, which was cyclized by bis(trimethylsilyl)acetamide to the 6-ethoxy derivative VII.Ammono- and methanolysis of intermedia

The Synthesis of (R)-2',3'-Dihydroxypropyl 5-Deoxy-5-dimethylarsinyl-β-D-riboside, a Naturally Occurring Arsenic-Containing Carbohydrate

The synthesis of the title compound, isolated from the brown kelp (Ecklonia radiata) or the giant clam (Tridacna maxima), is reported.Glycosidation of 1-O-acetyl-2,3,5-tri-O-benzoyl-β-D-ribose, either directly with (S)-1,2-di-O-benzylglycerol or via the derived orthoester with (S)-1,2-O-isopropylideneglycerol, led to two fully protected glycerol β-D-ribofuranosides.Subsequent chemical manipulations led to a common intermediate having a free hydroxy group at C 5 of the D-ribose residue.Replacement of this hydroxy group by a chlorine atom allowed the introduction of the dimethylarsinyl group at C 5 in a two-step procedure, and removal of protecting groups provided the natural product.

Syntheses and Structure Assignments of Six Azolinone Ribonucleosides

N-Ribosidation of a series of azolinones was achieved via silylation and SnCl4 catalysis.N-Ribosidation of 4-imidazolin-2-one gave 1-β-D-ribofuranosyl-4-imidazolin-2-one; of 1,2,4-triazolin-3-one gave 2- and 4-β-D-ribofuranosyl-1,2,4-triazolin-3-one, and 2,4-di-β-D-ribofuranosyl-1,2,4-triazolin-3-one; and of 2-tetrazolin-5-one gave 1-β-D-ribofuranosyl-2-tetrazolin-5-one and 1,4-di-β-D-ribofuranosyl-2-tetrazolin-5-one.Structure assignments were based on NMR and mass spectra, microanalytical data, and interconversions.The triazolinone monoriboside isomer structures were differentiated by 13C NMR long-range coupling patterns, and the assignments were confirmed by X-ray crystallography.New syntheses were developed for several of the ribonucleosides by fashioning the azolinone rings from 2,3,5-tri-O-benzoylribofuranosyl isocyanate.
