• Metallocalix[ n ]arene complexes as catalysts in numerous catalytic reactions. The presence of the calixarene cavity allows for enhanced enantioselectivity. Cross-coupling, olefin oxidation and polymerization processes are most studied. Increased attention to ROP cyclic esters produce biodegradable polymers. Large flexible calix[ ]arenes can adapt energy requirements a process. Aside from the...
In the title compound, C(15)H(19)ClN(2)OS, the dihedral angle between the amide and thio-urea fragments is 58.07 (17)°. The cyclo-hexane group adopts a chair conformation and is twisted relative to the thio-urea fragment, forming a dihedral angle of 87.32 (18)°. In the crystal, N-H⋯S hydrogen bond links the mol-ecules into chains running parallel to the a-axis direction.
In the process of optimization, we developed a novel core skeleton of thieno[3,4-b]pyrazine via GK-13. The derivatives synthesized were shown to inhibit TGase 2 activity in cancer cells. Some of the hit compounds such as the arylethynyl group-coupled thieno[3,4-b]pyrazine derivatives were shown to exhibit promising activity for use as potential therapeutic small-molecules in renal cancer by inh...
