(Chemical Equation Presented) The tetrahydro-pyrano[3,4-b]indoles 6 were synthesized from 2-(2-trimethylsilanyl-1H-indol-3-yl)-ethanols 5 and various ketones or aldehydes through silicon-directed oxa-Pictet-Spengler cyclizations. An unusual reaction led to the dimeric products 7 when some of 5 was treated with acetone using BF3 as the catalyst.

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 Pd(II)-catalyzed direct synthesis of benzo[a]carbazoles has been achieved through aminopalladation of alkynes, followed by intramolecular nucleophilic addition of the generated carbon-palladium bond to a tethered cyano/aldehyde group. Compared to literature procedures, this synthetic approach is operationally simple, uses simple substrates, and offers a fast intramolecular assembly resulting in the direct synthesis of benzo[a]carbazoles in which a wide variation of substituents at different sites is well-tolerated, leaving enough opportunity for diversification.
