Here, we account the synthesis and characterization of a series of symmetrical fused heterocyclic aromatic hydrocarbons (HAHs) with an indolo[1,2-c]quinazoline (IQ) as the core moiety. All the new HAHs IQ series were systematically investigated by using various spectroscopic methods. Furthermore, their photo-physical properties were supported by density functional theory (DFT) and time-dependent density functional theory (TDDFT) studies to support the experimental findings. The tetramethyl-substituted indolo[1,2-c]quinazoline (TMIQ) compound is shown to exhibit the shifted type of π–π stacking interactions, which render this series as a new semiconducting material. Single-crystal-based field-effect transistor devices of TMIQ exhibited efficient charge transport behavior, giving a p-channel field-effect mobility of 0.25 cm2?V?1?s?1 with an on/off ratio of 5 × 105.

A second generation polyphosphoric acid-mediated one-pot three-component synthesis of indoloquinoline scaffold is developed. This improved version of the process involves electrophilically activated nitroalkanes for the installation of strategic C-C and C-N bonds and ring C assembly. This modification allows the elimination of unnecessary solvent change operations and all steps are carried out in a true, uninterrupted one-pot manner. A further improvement involves the possibility to install an ortho-amino group in situ. A synthetic application of this method is showcased by the concise synthesis of an isocryptolepine alkaloid and its synthetic analogs with potent anticancer activities.

An efficient, green, and novel method for the synthesis of N-heterocycle-fused quinoxalines is reported herein. Dimethyl sulfoxide was used as both a reactant and a solvent in this reaction. A wide range of products in moderate to excellent yields were obtained, including pyrrolo[1,2-a]quinoxalines, indolo[1,2-a]quinoxalines, 1H-pyrrolo[3,2-c]quinolines, and benzo[4,5]imidazo[1,2-c]quinazolines.

A green method to synthesize cinnolines by 6π electrocyclic reaction with alkenyl amines and TBN has been developed. TBN plays a dual role both as a nitrogen atom source and an oxidant in this procedure. Relevant mechanism experiments reveal that the reaction proceeds through electrocyclic reaction and with diazo hydroxide as a key intermediate.
