In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 1585-90-6, name is 1-(2-Hydroxyethyl)-1H-pyrrole-2,5-dione, introducing its new discovery. Formula: C6H7NO3
lambda-Orthogonal pericyclic macromolecular photoligation
A photochemical strategy enabling lambda-orthogonal reactions is introduced to construct macromolecular architectures and to encode variable functional groups with site-selective precision into a single molecule by the choice of wavelength. lambda-Orthogonal pericyclic reactions proceed independently of one another by the selection of functional groups that absorb light of specific wavelengths. The power of the new concept is shown by a one-pot reaction of equimolar quantities of maleimide with two polymers carrying different maleimide-reactive endgroups, that is, a photoactive diene (photoenol) and a nitrile imine (tetrazole). Under selective irradiation at lambda= 310-350 nm, any maleimide (or activated ene) end-capped compound reacts exclusively with the photoenol functional polymer. After complete conversion of the photoenol, subsequent irradiation at lambda = 270-310 nm activates the reaction of the tetrazole group with functional enes. The versatility of the approach is shown by lambda-orthogonal click reactions of complex maleimides, functional enes, and polymers to the central polymer scaffold.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 1585-90-6, and how the biochemistry of the body works.Formula: C6H7NO3
