Abstract: We report a Pd-catalyzed route to heterocycles bearing a tetrasubstituted alkene fragment. Our approach merges the intramolecular carbopalladation of tethered alkynes with an alkylation step produced by the C–C cleavage of cyclobutanol derivatives. An alkenyl-Pd(II)… read more here.

Abstract: Benzofused nitrogen heterocycles are prevalent as key core structural motifs in functional molecules. Major syntheses of benzofused nitrogen heterocycles focus on construction of the heterocyclic ring starting from (poly)substituted benzene derivatives. Given that polysubstituted benzene… read more here.
