摘要:在这项工作中,进行了机理研究,以了解 Smi2/h2O 介导的 N-酰基恶唑烷酮与丙烯酸酯和丙烯酰胺的偶联,分别提供 γ-酮酯和酰胺.我们的结果提供了实验证据,表明二碘化钐可以促进通过与羰基底物的分子间自由基加成反应形成 Cc 键.与 N-环丙基羰基-2-恶唑烷酮的偶联反应表明 α,β-不饱和酯/酰胺被低价镧系元素试剂还原,而不是最初提出的 N-酰基恶唑烷酮 (J. Am. Chem. Soc. 2005),127,6544).速率测量支持在 N-酰基恶唑烷酮存在下通过 Smi2/h2O 优先还原丙烯酸酯或丙烯酰胺.在不存在 N-酰基恶唑烷酮的情况下,Smi2/h2O 促进丙烯酸酯的二聚化,而丙烯酰胺的 C=c 键减少.此外,Cbz 保护的苯丙氨酸的 Pfp 酯与丙烯酰胺的偶联仅导致丙烯酰胺和回收酯的还原,而与 N-酰基恶唑烷酮衍生物的相同偶联提供了 γ-酮酰胺.这些结果意味着不能发

标 题:Cosmetic with enhanced collagen I synthesis

摘要:A cosmetic including two different systems for procurement of actives in the human skin and enhancing the collagen I synthesis. The cosmetic with enhanced collagen I synthesis can include 0.001 to 2% by weight, related to the total weight of the cosmetic, of a first retinol-containing system including retinol encapsulated in a chitosan and carboxymethyl cellulose shell, 0.001 to 3.5% by weight, related to the total weight of the cosmetic, of a second retinol-containing system including cationic liposomes composed of phospholipids and with a quaternary fatty acid monoamine with C 21 -C 23 alkyl residue and the difference to 100% by weight of cosmetic subsidiaries. Very small amounts of retinol in combination with both transport systems show a remarkable effect on the synthesis of collagen I in comparison with one or more other known combinations of retinol derivatives or encapsulated systems.

标题:Synthesis of energetic thermoplastic elastomers containing both polyoxirane and polyoxetane blocks
发明人：SANDERSON ANDREW J; EDWARDS WAYNE; CANNIZZO LOUIS F; WARDLE ROBERT B
权利人:ALLIANT TECHSYSTEMS INC
摘要:This thermoplastic elastomer is present in a substantially solid state suitable for use as a binder for a propellant, explosive, and/or gas generant of a supplemental restraint system. The thermoplastic elastomer is formed from a composition including A blocks which are crystalline at temperatures below about 75° C. and B blocks which are amorphous at temperatures above about −20° C. The A blocks are derived from oxetane derivatives and the B blocks are derived from oxiranes and derivatives thereof. The A blocks and B-blocks are end-capped with a diisocyanate having a first isocyanate moiety that is substantially more reactive with the terminal groups of the blocks than the second isocyanate moiety, whereby the more reactive first isocyanate moiety is capable of reacting with the terminal groups of the blocks, leaving the less reactive second isocyanate moiety free and unreacted. The end-capped A blocks and the end-capped B blocks are linked together with a linking compound having two isocyanate-reactive groups which are sufficiently unhindered to react with the free and unreacted isocyanate moieties of the end-capped polymers.

权利人:UNIV OKLAHOMA
摘要:A composition comprising a carrier and prostaglandin effective in stimulating synthesis of melanin in a human melanocyte thereby enhancing pigmentation of the human skin and optionally comprising a lysosomotropic agent, a phosphodiesterase inhibitor, and/or methylxanthines, and a method of use of the composition. Use of this composition promotes tanning of the human skin and increases photoprotection from ultraviolet radiation.

摘要:A process for synthesizing 4,10-dinitro-2,6,8,12-tetraoxa-4,10-diazatetracyclo-[5.5.0.0 5 ,9 0 3 ,11 ]-dodecane ('TEX') involves combining at least one hexa-substituted piperazine derivative with a medium containing at least one nitronium anion source and at least one acid sufficiently strong to generate nitronium anions from the nitronium anion source. According to this invention, TEX yield is significantly improved by pre-heating the medium to 55° C. to about 70° C. and maintaining the medium from 55° C. to about 70° C. to permit the hexa-substituted piperazine derivative and nitronium anions to react and form the TEX. At least one NO x scavenger is added to the medium, preferably before the addition of the hexa-substituted piperazine derivative, to increase TEX yield.

标题 :Method for the synthesis of thermoplastic elastomers in non-halogenated solvents
发明人：SANDERSON ANDREW J; EDWARDS WAYNE
权利人:CORDANT TECH INC; SANDERSON ANDREW J; EDWARDS WAYNE
摘要:A method of preparing a thermoplastic elastomer having A blocks which are crystalline at temperatures below about 75 °C and B blocks which are amorphous at temperatures above about -20 °C is disclosed. The A blocks are derived from oxetane derivatives and/or tetrahydrofuran derivatives. The B blocks are derived from oxetanes, tetrahydrofuran, oxiranes, and derivatives thereof. The A blocks and B blocks are dissolved into solution containing a non-halogenated solvent, preferably tetrahydrofuran. The dissolved A blocks and B blocks are dried of water by azeotropic distillation of the non-halogenated solvent. Next, the dried A blocks and the dried B-blocks are end-capped with a diisocyanate having one isocyanate moiety substantially more reactive with the terminal groups of the blocks than the other isocyanate moiety, whereby the more reactive isocyanate moiety is capable of reacting with the terminal groups of the blocks, leaving the less reactive isocyanate moiety free and unreacted. The end-capped A blocks and the end-capped B blocks are linked together with a linking compound having two isocyanate-reactive groups which are sufficiently unhindered to react with the free and unreacted isocyanate moieties of the end-capped polymers.

摘要:The present invention provides a method of making a methylene malonate monomer that includes the steps of reacting a malonic acid ester with a source of formaldehyde optionally in the presence of an acidic or basic catalyst and optionally in the presence of an acidic or non-acidic solvent to form reaction complex. The reaction is optionally performed in the presence of or contacted with an energy transfer means such as a heat transfer agent, a heat transfer surface, a source of radiation or a laser such that reaction complex is substantially vaporized to produce a vapor phase comprising methylene malonate monomer which may be isolated. The present invention further provides methylene malonate monomers prepared by the method of the invention, as well as compositions and products formed from the methylene malonate monomers, including monomer-based products (e.g., inks, adhesives, coatings, sealants or reactive molding) and polymer-based products (e.g., fibers, films, sheets, medical polymers, composite polymers and surfactants).
