Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 4144-22-3, is researched, Molecular C8H11NO2, about One-pot Synthesis of Oxindoles through C-H Alkylation and Intramolecular Cyclization of Azobenzenes with Internal Olefins, the main research direction is azobenzene alkene dicarbonyl rhodium alkylation catalyst; alkylated azobenzene regioselective preparation zinc reductive intramol cyclization; oxindole preparation.SDS of cas: 4144-22-3.
The rhodium(III)-catalyzed site-selective C-H alkylation of azobenzenes and internal olefins, such as maleimides, maleates and fumarates, followed by reductive intramol. cyclization is described. A cationic rhodium catalyst in the presence of acetic acid additive in dichloroethane solvent was found to be the optimal catalytic system for the construction of ortho-alkylated azobenzenes, which smoothly underwent the intramol. cyclization leading to the formation of C3-functionalized oxindoles I (X = NH, O; R1 = H, 2-Me, 2-Et, 4-Me, etc.;R2 = Me, Et, Bn, n-Bu, etc.) in the presence of zinc powder and acetic acid. The formed oxindole scaffold could be an important asset towards the development of novel bioactive compounds
