摘要:The present invention relates to a cost-effective process for the synthesis of hyper-production of poly gamma glutamic acid using L-glutamic acid independent approach. Specifically, the present invention relates to the synthesis of poly gamma glutamic acid (γ-PGA) from jaggery, blackstrap molasses, and floral waste. More particularly, the present invention relates to a process for the synthesis of poly gamma glutamic acid in high yield and in the presence of Bacillus paralicheniformis NCIM 5769.

摘要:A mixed-bed catalytic system and its activation for direct synthesis of dimethyl ether from synthesis gas are described, comprising a catalyst for methanol synthesis and the zeolite ferrierite in its acid form as the methanol dehydrating component, the two being mixed physically in the form of powder of defined granulometry or as pellets. Another object of the present invention is a process for production of the acid form of the zeolite ferrierite. Another object of the present invention is a process for direct synthesis of dimethyl ether from a synthesis gas, using the catalytic system of the present invention.

摘要:The present invention relates to efficient processes useful in the preparation of fluorinated nucleosides, such as (2S,3R,4S,5R)-5-(2-amino-6-oxo-1,6-dihydro-9H-purin-9-yl)-3-fluoro-4-hydroxy-2-(mercaptomethyl)tetrahydrofuran-3-yl dihydrogen phosphate, also known as 3′-fluoro-thio-guanosine monophosphate or 3′-F-thio-GMP. 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. (I)
