Visible-Light-Mediated Regioselective Chlorosulfonylation of Alkenes and Alkynes: Introducing the Cu(II) Complex [Cu(dap)Cl<sub>2</sub>] to Photochemical ATRA Reactions
photocatalyzed protocol utilizing copper–phenanthroline-based catalysts has been developed that can convert a large number of olefins into their chlorosulfonylated products. Besides the Cu(I) complex [Cu(dap)2]Cl, now well-established in photo-ATRA processes, the corresponding Cu(II) complex [Cu(dap)Cl2] proved to be often even more efficient in the title reaction, being advantageous from an economic point of view
已经开发出一种利用铜-菲咯啉基催化剂的可见光介导的光催化方案,该方案可以将大量烯烃转化为其氯磺酰化产物。除了现在在光ATRA工艺中已经确立的Cu(I)络合物[Cu(dap)2 ] Cl之外,相应的Cu(II)络合物[Cu(dap)Cl 2 ]常常在光催化ATRA工艺中更有效。标题反应,从经济角度来看是有利的,但也为光氧化还原催化开辟了新途径。此外,由于它们通过内球机理稳定或与瞬态自由基相互作用的能力,铜配合物的性能优于常用的钌,铱或有机染料基光催化剂。化学计量的Na 2 CO 3的使用与不需要添加剂的活性烯烃相反,发现与铜光催化剂组合使用对将未活性烯烃转化为所需产物是必不可少的。如适当的对照实验所建议的,Na 2 CO 3的作用归因于防止催化剂中毒。

disclose the design of novelinhibitors 47 and 48 based on the X-ray structure of compound 5 bound to the HIV-1protease, their synthesis and activity against HIV-1protease. By making changes at the C4 position and the carbamate linkage the above compounds 47 and 48 were found to be approximately one hundred fold more active compared to 5 and their Ki values are in the picomolar range. An unusual observation
