A synthetic route to [3.4]-spirooxindoles based on cascade carbopalladation reactions of 1,4-dienes was described. While carbopalladation of alkenes have been used to access mainly [4.4]- or [4.5]-spirocycles, 4-exo-trig carbopalladation was not been yet applied to the synthesis of relevant [3.4]-spirooxindole scaffolds bearing a cyclobutyl ring. In addition, the cascade reaction generates an exocyclic double bond that can serve as a platform to further diversify the substitution pattern of the spirooxindole nuclei. The experimental part of the paper was very detailed, including the reaction process of 2-Bromopyridin-3-amine(cas: 39856-58-1Name: 2-Bromopyridin-3-amine)
2-Bromopyridin-3-amine(cas: 39856-58-1) belongs to anime.Typically the presence of an amine functional group is deduced by a combination of techniques, including mass spectrometry as well as NMR and IR spectroscopies. 1H NMR signals for amines disappear upon treatment of the sample with D2O. In their infrared spectrum primary amines exhibit two N-H bands, whereas secondary amines exhibit only one.Name: 2-Bromopyridin-3-amine
