标题:Synthesis of 1,4-trans-polybutadiene using a lanthanide organic acid salt catalyst
发明人：LYNCH THOMAS J
权利人:BRIDGESTONE CORP
摘要:The invention provides a catalyst composition, comprising: (a) an organolithium compound; and, (b) an organic acid salt of lanthanide series element; wherein: (1) only components (a) and (b) are required to promote the synthesis of 1,4-trans-polybutadiene; (2) the ratio of component (a) to component (b) is selected to maximize formation of the trans structure of said 1,4-trans-polybutadiene; and, (3) components (a) and (b) are selected for enabling further diblock synthesis. The invention further contemplates a process for using the catalyst to synthesize 1,4-trans-polybutadiene and other polymers and copolymers having trans configuration in the conjugated diene monomer contributed units.

摘要:The invention provides synthetic methods for the preparation of cantharidin and analogs thereof. In one aspect, the invention provides an improved Diels-Alder cycloaddition to generate a key intermediate en route to cantharidin and analogs thereof. In certain embodiments, the new Diels-Alder reaction involves reacting Compound (2) in the presence of furan, and in the absence of acid or increased pressure, in an aprotic polar solvent with slight warming, to yield Compound (1) in favorable yield and exo-endo ratio. In another aspect, the invention also provides a new Diels-Alder reaction between compounds of Formula (III) and furan to yield compounds of Formula (IV), which can then be transformed into cantharidin or analogs thereof. In yet another aspect, the invention describes a new palladium-mediated carbonylation providing another key intermediate en route to cantharidin and analogs thereof. In addition to synthetic methods, present invention also provides compounds (i.e., intermediates) useful in the synthesis of cantharidin and analogs thereof. Compounds provided herein may have biological activity, and therefore may be used in the treatment of diseases or conditions (e.g., infectious diseases and skin conditions).

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.
