Novel Carboranyl Derivatives of Nucleoside Mono- and Diphosphites and Phosphonates: A Synthetic Investigation
نویسندگان
چکیده
A number of nucleoside mono- and diphosphites and phosphonates containing 1,2-dicarbadodecaborane (12) (la-6b) at 5'-position of the sugar moiety have been synthesized in good yields. Experimental details along with the spectroscopic and analytical data, supporting the formation of the title compounds, are presented. These constitute a new generation of boron compounds that are envisioned to be useful in cancer treatment via Boron Neutron Capture Therapy (BNCT).

Novel Oxadiazole Thioglycosides as Potential Anti- Acinetobacter Agents
The glycosylation of 1,3,4-oxadiazole-2-thiones has been performed with peracetylated β-pyranosyl bromide in the presence of potassium carbonate. Deprotection of acetylated thioglycosides was necessary for increasing their antibacterial effects. The structure of nucleosides were confirmed by 1H NMR, 13C NMR and HRMS. The anomeric protons of nucleosides c1–4 were assigned to the doublet, confirm...

متن کاملTheoretical investigation on the aromaticity of mono-substituted benzene derivatives by using cyclic reference
The degree of aromaticity of mono-substituted derivatives of benzene has beeninvestigated using a new index based on electric field gradient index, by using two mechanicalquantum methods with Gaussian 03. Two different basis sets have applied to study and theresults compared. This strategy has demonstrated that, due to violation of symmetry in have pisystems,how the degree of aromaticity can ha...
