摘要:Novel phosphonate compounds are described. The compounds have activity as neuraminidase inhibitors against wild-type and H274Y mutant of H1N1 and H5N1 viruses. The present disclosure also provides an enantioselective synthetic route to known neuraminidase inhibitors oseltamivir and the anti-flu drug Tamiflu®, as well as novel phosphonate compounds, via D-xylose. Another efficient and flexible synthesis of Tamiflu and the highly potent neuraminidase inhibitor Tamiphosphor was also achieved in 11 steps and >20% overall yields from the readily available fermentation product (1S-cis)-3-bromo-3,5 -cyclohexadiene-1,2-diol. Most of the reaction intermediates were obtained as crystals without tedious purification procedures. The key transformations include an initial regio- and stereoselective bromoamidation of a bromoarene cis-dihydrodiol, as well as the final palladium-catalyzed carbonylation and phosphonylation.

标题 :Process for synthesis of lignocellulosic based bioproducts
发明人：JAIN ARPAN
权利人:JAIN ARPAN
摘要:The present invention relates to a process for the synthesis of lignocellulosic-based bioproducts. The process involves the biochemical conversion of lignocellulosic biomass generated through agriculture, non-agriculture, and forest that produces streams of high-value goods including cosmetic ingredients, nutraceuticals, carbon fiber, activated carbon, graphene, low-calorie sugar, bioplastic, cellulose pulp, and nano-cellulose based aerogel. The process comprises; a process stage-1 for removing the phenolic compounds (lignin) from lignocellulosic biomass as well as decreasing the crystallinity of the cellulose using alkaline modified ethyl-hydro-oxides (m-EHOs) extraction, a process stage-2 for removal of the hemicellulose fraction of the holocellulose using mild sulfuric acid extraction, and a process stage-3 for chemically treating cellulose pulp with alkaline modified ethyl-hydro-oxides (m-EHOs) solvent for the production of nano-cellulose and micro-cellulose fractions. Along with the production of high-value goods, the process generates energy.
