Abstract: Abstract Phenylmethylidene-bis(pyrrolo[2,3-b]quinoxaline) derivative (1) was synthesized by the reaction between the 3-thiobenzoylpyrrolo[2,3-b]quinoxaline (SPQ) and a secondary amine or NaOH in DMF solution. The obtained compound was characterized by single crystal X-ray diffraction, which indicated the… read more here.

Abstract: ABSTRACT The unexpected result for the formylation of N-ethylcarbazole under the Vilsmeier–Haack conditions (POCl3/DMF) led to the synthesis of novel methylene bridged bis-pyrrolo[3,2-c]carbazoles via Hemetsberger indole synthesis was reported. A plausible mechanism for the formation… read more here.
