The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature. 103146-25-4, Name is 4-(4-(Dimethylamino)-1-(4-fluorophenyl)-1-hydroxybutyl)-3-(hydroxymethyl)benzonitrile, SMILES is N#CC1=CC=C(C(O)(C2=CC=C(F)C=C2)CCCN(C)C)C(CO)=C1, in an article , author is Roosta, Atefeh, once mentioned of 103146-25-4, SDS of cas: 103146-25-4.
Efficient and Chemoselective Procedure for Conversion of Rhodanine Derivatives into 1,3-Thiazolidine-2,4-diones via 1,3-Dipolar Cycloaddition Reaction and Rearrangement Sequences
Herein, we report a chemoselective 1,3-dipolar cycloaddition reaction between 5-alkylidene- or 5-arylidene rhodanine derivatives and nitrile oxide generated in situ from dibromoformaldoxime to construct 1,3-thiazolidine-2,4-dione scaffold under mild conditions. This strategy exhibits a distinguished manner to afford thiazolidine derivatives in a simple, rapid and practical route. The results proved that the reaction proceeds through an unpredictable rearrangement and no spirocyclic product is generated. The structures of the target molecules were confirmed by IR, H-1 NMR, C-13 NMR, mass spectra and unambiguously X-ray crystal structure analysis.
