摘要:在批处理实验中使用一致的实验条件研究了八种模型污染物与九种颗粒状fe(0)的反应.模型污染物(由于被铁金属还原而称为"还原物")包括阳离子(cu2 +),阴离子(cro4(2-),No3(-)和5,5',7,7'-靛蓝四磺酸盐)和中性物质(2-氯苯乙酮,2,4,6-三硝基甲苯,四氯化碳和三氯乙烯).该还原物范围的多样性为fe(0)的反应性提供了独特的广阔视野.还原物消失的速率常数对于特定的还原物变化多达四个数量级(由于九种铁类型的差异),但是还原物之间的差异甚至更大,几乎超过七个数量级.汇总数据的各种方法都表明,与fe(0)的相对反应性依次变化为cu2 +,5,5',7,7'-靛四磺酸盐> 2-氯苯乙酮,2,4,6-三硝基甲苯>四氯化碳,Cro4 (2-)>三氯乙烯> No3(-).尽管还原剂对消失动力学的影响最大,但由于fe(0)的类型,反应性之间的细微差别表明cro2(2-)和no3

标题:Process for the synthesis of 2-hydroxyphenyl alkyl ketones
发明人：BORZATTA VALERIO; POLUZZI ELISA; VACCARI ANGELO
权利人:ENDURA SPA
摘要:A process is described for the synthesis of 2-hydroxyphenylalkyl ketones, by means of catalytic rearrangement of phenolic esters. This process is characterized by the use, as catalysts, of crystalline aluminosilicates of the pentasyl type having predefined values of silica/alumina ratio, grain size, surface area and porosity, and containing between 10 wt% and 40 wt% of finely ground alumina as bonding agent. The rearrangement thus catalyzed involves a high conversion of the phenolic ester, a high orthoselectivity and a low formation of phenolic by-products, thus enabling the formation of the end product in high yields. In particular, the process applies to the synthesis of 2-hydroxyacetophenone.

摘要:Disclosed are methods for the synthesis of chiral alcohols by Sortase A-mediated oxidoreductase oligomers, which relates to the field of biocatalysis. In the present disclosure, oxidoreductase oligomers were used as biocatalysts for chiral alcohol preparation. Compared to wild-type enzymes, the oxidoreductase oligomers significantly improved catalytic activity and thermal stability. The sortase A-mediated oxidoreductase oligomers had 6-8 folds improvement in specific activity over that of the wild-type enzymes. The oligomers displayed a T m value 6-12° C. higher than that of the wild-type, suggesting the sortase A-mediated oxidoreductase oligomers significantly improved thermostability of the enzymes. The oxidoreductase oligomers catalyzed asymmetric transformation to produce (S)-1-phenyl-1,2-ethanediol or (R)-1-phenethyl alcohol within 3-6 hr, with an optical purity of 98%-100% and a yield of 98%-99%.

摘要:New chiral phosphinopyrrolidine compounds of the general formula: (I) or (I') wherein R1 is a hydrogen atom, -COR, -COOR, -CONHR or -SO2-R where R is an alkyl or aryl group, R2 and R3 each represents independently an aryl group which may have a substituent or substituents, and R4 and R5 each represents independently an aliphatic or cycloaliphatic hydrocarbyl group which may have a substituent or substituents, as well as the use of these compounds as ligand for a metal complex catalyst for asymmetric synthesis of optically active compounds. The new chiral phosphinopyrrolidine compounds are useful ligands which attain both of high optical yield and high reaction efficiency in catalytic asymmetric reduction.
