摘要:The synthesis of star polymers having well-defined arms emanating from well-defined and readily controllable calix n!arene (n=4 to 16) cores are described. The synthesis is particularly suitable for polyisobutylene and/or polysiloxane star polymers. The synthesis has been achieved using carbocationic and/or anionic ring-opening polymerization techniques to form polymer arms of desired molecular weights, then separately preparing the calixarene derivative core, and finally, linking the arms to the core by transesterification or hydrosilation.

摘要:The invention provides a method for manufacturing or preparing neutral, low molecular weight 99m Tc-labeled and 186 Re-labeled carbohydrate complexes with an improved radiochemical yield from a simple functionalized sugar, such as glucosamine. In particular the synthesis relies on single ligand transfer (SLT) or double ligand transfer (DLT) reactions for converting a ferrocene compound into a rhenium or technetium tricarbonyl complex. The ferrocene compound may be linked to a sugar through various functional groups including, for example, thio, amino and alcohol functionalities to provide a wide range of radiolabeled sugar complexes that include both water soluble and relatively water insoluble compounds.

摘要:A method is described for synthesizing and administering carotenoid compounds with improved antioxidant characteristics. In some embodiments, extension or improvement of conjugation may be employed in structural modification of carotenoids. In other embodiments, reduction of ring/chain steric hindrance may improve the lambda max, and hence, the overall antioxidant capability, of particular compounds. In other embodiments, introduction and/or increase in synthetic handles for conjugation may improve the stoichiometric ratios of conjugating moieties to the polyene backbone. The methods may be used to improve natural and/or synthetic compounds for medicinal application in the treatment of disease.

权利人:RHONE POULENC CHIMIE
摘要:p-Dihydroxylated aromatic compounds are prepared via the oxidation of p-fuchsones, the latter advantageously being synthesized by reacting a phenolic compound having at least one hydrogen atom in the para-position to the hydroxyl function with a non-enolizable ketonic compound, in the presence of a catalytically effective amount of an acid catalyst and, optionally, a cocatalytically effective amount of an ionizable sulfur-containing compound.

标题 :Synthesis of polyfunctional polyol acrylates

摘要:A method of synthesizing urethane-free polyfunctional acrylate compounds. The method includes reaction of a polyol with acrylic acid in the presence of an inhibitor. A catalyst may also be present. The catalyst may be an acid and the inhibitor may be a substituted phenol compound. Excess acid may be removed by adding a salt and excess water may be removed by adding a drying agent. The reaction converts alcohol groups of the polyol to acrylate groups to provide a radiation-curable polyfunctional acrylate compound. The reaction is applicable to polyols generally and provides a scalable high yield process for forming urethane-free polyfunctional acrylates over a wide range of molecular weights. Coatings made from the acrylate products exhibit modulus and tensile strength characteristics favorable for primary fiber coatings.
