Syntheses of benzo[c] and naphtho[c]heterocycle diesters and dinitriles were achieved via our newly developed iterative elongation protocol. The photophysical and electrochemical properties of these conjugated systems are explored.
[Show abstract][Hide abstract] ABSTRACT: Synthesis of symmetrical and unsymmetrical naphth-annelated thienyl heterocycles has been achieved via thionation of hydroxyketones/diketones using Lawesson's reagent. Photophysical studies of 1,3-disubstituted naphtho[c]thiophene analogs are presented. Electro-oxidative behavior of these naphtha-annelated thiophenes are investigated using cyclic voltammeter.
[Show abstract][Hide abstract] ABSTRACT: Two efficient palladium-catalyzed intramolecular α-arylation reactions of α-amino acid esters have been developed that allow either 1-isoindolecarboxylic acid esters or the corresponding isoindolines to be selectively synthesized simply by a slight change of reaction conditions.

[Show abstract][Hide abstract] ABSTRACT: An efficient palladium/copper-catalyzed approach to the synthesis of highly substituted 3-formyl furans from the reactions of readily available α-bromoenaminones with terminal alkynes has been developed. This methodology was realized by the cascade reactions of Sonogashira coupling and the subsequent intramolecular cyclization.
