摘要:钌基催化剂在通过乙炔氢氯化生产聚氯乙烯中的潜在应用受到阻碍,因为它们的活性和稳定性均比金基体系低,尽管价格低4倍.结合深入的表征和动力学分析,我们揭示了掺杂在氮掺杂碳(nc)上的最佳纳米尺寸为1.5 Nm的钌纳米粒子的优越活性,并确定了它们的失活模式:1)纳米粒子再分散为非活性单原子和2)焦炭在金属部位形成.调节nc载体的密度可以在1073 K下将钌纳米颗粒催化包封到单层石墨烯壳中,从而防止不希望的金属再分散.最后,

摘要:Provided is a method for fully liquid-phase synthesis of a GRnH nonapeptide amide analog, which belongs to the technical field of medicine synthesis. The method comprises respectively synthesizing a 'Trp-Ser-Tyr' fragment, an 'R-Leu' fragment, a 'Pyr-His' fragment and 'Arg-Pro-Hunan T', wherein, R = D-Ala (alarelin), D-Leu (leuprorelin), D-Trp (deslorelin) and D-His (histrelin), and obtaining the GRnH nonapeptide amide analog with high yield and high purity by means of a '3 +2 +2 +2' fragment condensation method. The synthesis method is environmentally friendly, mild, and free of any highly toxic and poisonable reagents. The cost is greatly reduced and the synthesis method is very suitable for large-scale production.

摘要:The present invention provides a process for the synthesis of opioid prodrugs. In particular, the present invention provides a process for the synthesis of opioid prodrugs comprising: treating an opioid, in the form of a salt or a freebase, with a carbonyl synthon to form an activated intermediate and subsequently reacting the activated intermediate with an amine, in the form of a salt or a freebase.

摘要:Provided is a method for the continuous synthesis of 2-cyclopenten-1-one. The continuous synthesis method comprises: loading a catalyst in a continuous reaction device, then continuously conveying cyclopentene, an oxidant and a solvent into the continuous reaction device for an oxidation reaction, and continuously discharging 2-cyclopentene-1-one. In the presence of the catalyst and the solvent, cyclopentene is used as a starting material, and same is directly oxidized by the oxidant, which can avoid the generation of a large amount of halogen-containing three wastes; at the same time, the entire continuous synthesis process is carried out in the continuous reaction device, which can effectively inhibit the occurrence of safety risks during scale-up production; in addition, after the reaction is complete, the product system of the oxidation reaction can be simply concentrated to obtain the target product (2-cyclopenten-1-one). Thus, the purity (up to 98% and above) and separation rate (up to 79%) of the product are greatly improved, and production can be easily scaled up.
