Azizollahi, Hamid published the artcileSynthesis of [3.4]-Spirooxindoles through Cascade Carbopalladation of Skipped Dienes, Recommanded Product: 2-Bromopyridin-3-amine, the publication is Advanced Synthesis & Catalysis (2020), 362(9), 1899-1904, database is CAplus.
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.
