We report an unusual face selective reduction of the exocyclic double bond in the α-methylene-γ-butyrolactone motif of spiro-oxindole systems I and II [R1 = H, Me, R2 = H; R1 =H, R2 = Me]. The spiro-oxindoles were assembled by an indium metal mediated Barbier-type reaction followed by an acid catalyzed lactonization. This study involved multiple reactions and reactants, such as 4,7-Dimethylindoline-2,3-dione (cas: 15540-90-6Application of 15540-90-6).
4,7-Dimethylindoline-2,3-dione (cas: 15540-90-6) belongs to indole derivatives. Indole, first isolated in 1866, and it is commonly synthesized from phenylhydrazine and pyruvic acid, although several other procedures have been discovered. Due to this activity, the indole ring system has become an important component or intermediate in the synthesis of heterocycles.Application of 15540-90-6
