标题:Process for the preparation of oseltamivir and methyl 3-epi-shikimate
发明人：RAWAT VARUN; DEY SOUMEN; ARUMUGAM SUDALAI
权利人:COUNCIL SCIENT IND RES
摘要:The present invention discloses high yielding enantioselective process for synthesis of Oseltamivir from readily available starting material, cis-1,4-butene diol. The process features incorporation of chirality using sharpless asymmetric epoxidation (AE) and diastereoselective Barbier allylation and construction of cyclohexene carboxylic acid ester core through a ring closing metathesis (RCM) reaction. Further also disclosed herein is synthesis of (−)-methyl 3-epi-shikimate.

标 题:Anionic polymers composed of dicarboxylic acids and uses thereof
发明人：SANDERS JOHN LARRY; MAZO GRIGORY; MAZO JACOB
摘要:Biodegradable anionic polymers are disclosed which include recurring polymeric subunits preferably made up of dicarboxylic monomers such as maleic anhydride, itaconic anhydride or citraconic anhydride. Free radical polymerization is used in the synthesis of the polymers. The polymers may be complexed with ions and/or mixed with fertilizers or seeds to yield agriculturally useful compositions. The preferred products of the invention may be applied foliarly or to the earth adjacent growing plants in order to enhance nutrient uptake by the plants.
