| Research Abstract |
Novel Pd-and Au-catalyzed molecular transformations have been developed through the modification of ligands and counter anions which showed high reactivity and selectivity. A variety of Norbornane derivatives have been synthesized and successfully used in the Pd-catalyzed asymmetric intramolecular hydroamination of alkynes. The newly prepared (R, R)-methyl norphos and (R, R)-toly renorphos afforded N-containing heterocyles in high yields and high enantio-selectivity. Moreover, novel Pd-catalyzed allylative dearomatization and three-component cycloaddition were developed. We have succeeded in development of cationic Au-catalyzed hydroalkoxylation and hydrothiolation. Moreover, we also succeeded in construction of thienocarbazole frameworks via a new Au-catalyzed cascade cyclization of arydiynes, which was further applied in the synthesis of D-A-D organic electronic materials. Various O-, S-and N-containing heterocyles bearing diiodine substituents have been synthesized through the facile and efficient electrophilic iodocyclizations.
