The presently described technology provides compositions of one or more of oxoacids, polyethylene glycols, and/or vitamin compounds chemically conjugated to dextrorphan, (+)-17-methylmorphinan-3-ol), to form novel prodrugs and compositions of dextrorphan.
A facile and general method for copper-catalyzeddecarboxylative alkylcarboxylation of cinnamic acids with dimethyl 2,2′-azobis(2-methylpropionate) has been developed. The scope and versatility of the reaction was demonstrated, and a broad range of substrates bearing electron-donating and -withdrawing groups on the aromatic rings were all compatible with this reaction to provide desired β,γ-unsaturated
terminal octahedral CoIIIN2O2 cores coordinate to the central octahedral CoII ion through μ2-phenoxido oxygen atom and the bridging carboxylato ions. In addition, the complexes (2 and 3) derived from reduced Schiff base ligand have, rather unusually, a terminally coordinated carboxylato ion to CoIII, which is acetonitrile molecule in case of complex (1) with unreduced ligand. Complex 2 has been found

A series of novel porphyrin-cinnamic acid (porphyrin/CA) conjugates (4a-4c) have been synthesized by condensation of 5-(4-Hydroxyphenyl)-10,15,20-triphenyl- porphyrin (1) with different substituted cinnamic acids (CAs) through an alkyl linker due to the biological activities of CAs and the application of porphyrins in photodynamic therapy (PDT) of cancer. Their related zinc (II) complexes (5a-5c) were
通过将5-(4-羟基苯基)-10,15,20-三苯基卟啉(1)与不同的取代肉桂酸缩合,合成了一系列新型的卟啉-肉桂酸(卟啉/ CA)共轭物(4a-4c)。由于CAs的生物学活性以及卟啉在癌症的光动力疗法(PDT)中的应用,导致通过烷基连接子(CAs)的转移。还制备了它们的相关锌(II)配合物(5a-5c)。这些新型化合物已通过1H NMR,红外(IR),质谱(Ms)和元素分析得到了充分表征。通过吸收和荧光光谱研究了这些靶分子的光物理性质。在溶液中,还通过紫外-可见光谱研究了pH,酸介质中的离子强度和浓度对4a聚集行为的影响。当pH值在THF水溶液中达到2.0时,变宽的红色Soret带变宽,表明J聚集体的形成。此外,在酸性介质中0.3 M NaCl的较高离子强度导致在THF水溶液中生成J聚集体。Soret带的显着蓝移也表明在THF中以1.1×10-4 M形成4a的H聚集体。
Copper(I)-Catalyzed α-Acryloyloxylation of Ketones with α,β-Unsaturated Carboxylic Acids To Form α-Acryloyloxy Ketones
acryloyloxylation of ketones with α,β-unsaturated carboxylic acids was developed through using copper (I) as the catalyst. The most concise approach to form α-acryloyloxyketones through direct oxidative coupling at α-C(sp3)-H of ketones. This method had a high productivity for the products and a wide range of application for both ketones and unsaturated carboxylic acids. A copper (I) catalyzed reaction mechanism
