One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 66-22-8, Name is Uracil, formurla is C4H4N2O2. In a document, author is Wani, Imtiyaz Ahmad, introducing its new discovery. Safety of Uracil.
Stereoselective Construction of Pyrazinoindoles and Oxazinoindoles via Ring-Opening/Pictet-Spengler Reaction of Aziridines and Epoxides with 3-Methylindoles and Carbonyls
A highly efficient and stereoselective route to access 1,3-disubstituted 1,2,3,4-tetrahydropyrazino[1,2-a]indoles and 3,4-dihydro-1H-[1,4]oxazino[4,3-a]indoles with excellent stereoselectivity (de, ee >99%)via base mediated ring opening of aziridines/epoxides with 3-methylindoles followed by BF3 center dot OEt2 catalyzed Pictet-Spengler reaction is accomplished. Interestingly, PTSA promoted cyclization led to the formation of oxidized 3,4-dihydropyrazino[1,2-a]indoles in excellent yields via an unprecedented Pictet-Spengler-detosylation cascade.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 66-22-8 help many people in the next few years. Safety of Uracil.
