Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 103816-19-9, molcular formula is C11H19ClN2O, introducing its new discovery. Application In Synthesis of [1,4′-Bipiperidine]-1′-carbonyl chloride
Methods for manufacturing 7-ethyl-10-[4-(1-piperidino)-1-piperidino]-carbonyloxy-camptothecin are described comprising I. reacting a mixture of 1-chlorocarbonyl-4-piperidinopiperidine hydrochloride and 7-ethyl-10-hydroxycamptothecin in a polar aprotic solvent with a base in the presence of catalytic amounts of a N-containing cyclic organic compound having 3 to 20 carbon atoms and optionally in the presence of a water binding agent in an amount which effectively binds any water present in the above reactants and solvents; or II. reacting: (a) 7-Ethyl-10-hydroxycamptothecin in a polar aprotic solvent with phosgene, trichlormethyl-chloroformate, bis(trichloromethyl)carbonate or a alternative to phosgene and a base in the presence of catalytic amounts of a N-containing cyclic organic compound having 3 to 20 carbon atoms; and (b) subsequently with piperidinopiperidine and an amine base.
One of the oldest and most widely used commercial enzyme inhibitors is aspirin, Application In Synthesis of [1,4′-Bipiperidine]-1′-carbonyl chloride, which selectively inhibits one of the enzymes involved in the synthesis of molecules that trigger inflammation. you can also check out more blogs about 103816-19-9
