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. 2999-46-4, Name is Ethyl 2-isocyanoacetate, formurla is C5H7NO2. In a document, author is Rodriguez-Ferrer, Patricia, introducing its new discovery. Computed Properties of C5H7NO2.
Chiral Bifunctional Thiosquaramides as Organocatalysts in the Synthesis of Enantioenriched 3,3-Disubstituted Oxindoles
Four novel chiral bifunctional thiosquaramides have been prepared from cyclopentyl dithiosquarates and diamines derived from natural l-Valine and l-tert-Leucine. The novel thiosquaramides have been tested as organocatalyst in the nitro-Michael addition of 3-substituted oxindoles to different beta-aryl-substituted nitroalkenes. The reaction occurred easily in high yields and excellent stereoselectivities, showing that the novel organocatalysts are much more effective than their thioureas and squaramides homologs.
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 2999-46-4 help many people in the next few years. Computed Properties of C5H7NO2.
