摘要:The present invention relates to efficient processes useful in the preparation of fluorinated nucleosides, such as (O—{[(2R,3R,4S,5R)-5-(6-amino-9H-purin-9-yl)-4-fluoro-3-hydroxyoxolan-2-yl]methyl}O,O-dihydrogen phosphorothioate, also known as 2′-(S)-fluoro-thio-adenosine monophosphate or 2′-F-thio-AMP. Such fluorinated nucleosides may be useful as a biologically active compound and or as an intermediate for the synthesis of more complex biologically active compounds. The present invention also encompasses intermediates useful in the disclosed synthetic processes and the methods of their preparation.

标题 :A process for the treatment of tail gases
发明人：LODHA DHANANJAY MAHENDRA
权利人:SHREE SULPHURICS PVT LTD
摘要:The present disclosure relates to a process for the treatment of tail gases. The process of the present disclosure is simple and environmentally friendly. The process of the present disclosure produces chlorosulfonic acid, which is a value-added reagent used in the synthesis of alkyl sulphates detergents, saccharin and the like. Further, the process of the present disclosure produces sulfuryl chloride, which is an important value added chlorinating agent in the organic synthesis/reactions.

标 题 :Pyrolysis of 2-sulfochloride benzoates
发明人：DIPIPPO CARMINE A
权利人:SCOTT PAPER CO
摘要:Ortho-sulfobenzoic anhydride is synthesized by pyrolysis of the 2-sulfochloride benzoates. The benzoate intermediates are readily prepared by reacting either the esters of dithiodibenzoic acid with chloride water or the 2-diazonium chloride benzoates with sulfur dioxide. The invention also provides for the total synthesis of saccharin, free of bitter tasting contaminants, from such reactants, the ultimate step in such synthesis being the ammonolysis of the o-sulfobenzoic anhydride.

摘要:A process for the synthesis of oligonucleotides using phosphoramidite chemistry is provided. The process employs as activator a 1,1-dioxo-1,2-dihydro-1λ6-benzo[d]isothiazol-3-one, preferably in the presence of an organic base. The 1,1-dioxo-1,2-dihydro-1λ6-benzo[d]isothiazol-3-one is represented by the following structural formula: wherein p is 0 or an integer from 1 to 4; X7 is O or S; R for each occurrence is a substituent, preferably each independently, a halo, a substituted or unsubstituted aliphatic group, —NR11R12, —OR13, —OC(O)R13, —C(O)OR13, or cyano; or two adjacent R groups taken together with the carbon atoms to which they are attached form a six membered saturated or unsaturated ring; R11 and R12 are each, independently, —H, a substituted or unsubstituted aliphatic group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted aralkyl group; and R13 is a substituted or unsubstituted aliphatic group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted aralkyl group. Preferred organic bases are pyridine, 3-methylpyridine, or N-methylimidazole.
