2,6-Dichloro-9-(2′,3′,5′-tri-O-acetyl-β-d-ribofuranosyl)-9H-purine
The title synthetic analog of purine nucleosides, C16H16Cl2N4O7, has its acetyl-ated β-furan-ose ring in a 3'β-envelope conformation, with the corresponding C atom deviating by 0.602 (5) Å from the rest of the ring. The planar part of the furan-ose ring forms a dihedral angle of 65.0 (1)° with the mean plane of the purine bicycle. In the crystal, mol-ecules form a three-dimensional network thro...
متن کاملPhotochemistry of 6-amino-2-azido, 2-amino-6-azido and 2,6-diazido analogues of purine ribonucleosides in aqueous solutions.
The photochemistry of 6-amino-2-azidopurine, 2-amino-6-azidopurine and 2,6-diazidopurine ribonucleosides has been investigated in aqueous solutions under aerobic and anaerobic conditions. Near UV irradiation of 6-amino-2-azido-9-(2',3',5'-tri-O-acetyl-β-D-ribofuranosyl)purine and 2-amino-6-azido-9-(2',3',5'-tri-O-acetyl-β-D-ribofuranosyl)purine in the presence of oxygen leads to efficient forma...
متن کامل3,4,6-Tri-O-acetyl-1,2-[(S)-ethylidene]-β-d-mannopyranose
In the title compound, C(14)H(20)O(9), the six-membered pyran and the five-membered dioxalane rings adopt chair and twisted conformations, respectively. In the crystal, the mol-ecules are linked by C-H⋯O inter-actions.

In the title compound, C(19)H(20)Cl(2)O(10), the hexopyranosyl ring adopts a chair conformation. The four substituents are in equatorial positions. The mol-ecules arelinked via C-H⋯O contacts along the a axis.
متن کاملSynthesis and Enzymic Hydrolysis of Acylated Adenosine Derivatives
Various derivatives of adenosine were prepared by acylation of adenosine (6-amino-9-(bD-ribofuranosyl)purine (1) with different molar equivalents of acetic anhydride and/or pivaloyl chloride in pyridine. Compounds 6-acetylamino-9-[(2,3,5-tri-O-acetyl)-b-Dribofuranosyl]purine (3), 6-amino-9-[(2,3,5-tri-O-acetyl)-b-D-ribofuranosyl]purine (4), and 6-pivaloylamino-9-[(2,3,5-tri-O-pivaloyl)-b-D-ribo...
