A Pd-catalyzed site-selective C(sp2)-H activation/cycloimidoylation of 2-isocyano-2,3-diarylpropanoates to construct diverse cyclic imine products has been developed. Six-membered 3,4-dihydroisoquinolines containing a C3 quaternary carbon center were generated dominantly by using bulky Ad2Pn-Bu as a ligand, while five-membered 1,1-disubstituted 1H-isoindoles were formed preferentially in the presence of bidentate phosphine ligand DPPB. The selectivity for 1H-isoindole formation was enhanced by using steric hindered aryl iodides. DFT calculations suggested that the exptl. observed ligand-controlled selectivity was a result of trans effect. The results came from multiple reactions, including the reaction of H-Phg-OEt.HCl(cas: 59410-82-1Product Details of 59410-82-1)
H-Phg-OEt.HCl(cas: 59410-82-1) belongs to esters. They are important in biology, being one of the main classes of lipids and comprising the bulk of animal fats and vegetable oils.Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones.Product Details of 59410-82-1
