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: 1265884-98-7, is researched, Molecular C34H22NO2P, about Tandem Allylation/1,2-Boronate Rearrangement for the Asymmetric Synthesis of Indolines with Adjacent Quaternary Stereocenters, the main research direction is indole boronate ester allylic acetate palladium allylation boronate rearrangement; indoline stereoselective preparation.Electric Literature of C34H22NO2P.
A three-component coupling using lithiated indoles, boronate esters and allylic acetates generates chiral indolines with adjacent quaternary stereocenters. Successful stereocontrol required the use of phosphoramidite ligands not previously described for organopalladium chem. Mechanistic studies indicate a monodentate PdL intermediate, and a stepwise allylation-aryl/alkyl migration. A protodeborylation strategy was used to install a C-H bond in place of the C-B bond. A photoredox coupling was used to replace C-B bond with a C-C bond in a highly diastereoselective manner. In the specific case of methyl-vinyl ketone, a novel radical-mediated annulation provides polycyclic products with high enantio- and diastereoselectivity.
