In heterogeneous catalysis, the catalyst is in a different phase from the reactants. category: oxazolidine, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 497-25-6, name is Oxazolidin-2-one. In an article，Which mentioned a new discovery about 497-25-6
A practical and expedient synthesis of the titled compounds is described. Using the same simple procedure (DBU was reacted with the mixture of an alkynol and a nitrogen heterocycle in CH2Cl2 at rt for 16 h), a wide variety of diverse NH-containing nucleophiles such as pyrazoles, indazoles, indoles, imidazoles and benzoimidazole, oxazolidinone and benzooxazolone, triazoles, phthalimides, and N-formyl anilines, have been reacted with 4-aryl-4-hydroxy-alkynyl esters to afford good yields of desired products. This reaction proceeded by the DBU catalyzed redox isomerization of ethyl 4-aryl-4-hydroxybut-2-ynoate to (E)-ethyl 4-aryl-4-oxobut-2-enoate, followed by the DBU catalyzed aza-Michael reactions with the isomerized product in one-pot.
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 497-25-6, help many people in the next few years.COA of Formula: C3H5NO2
