Molecules
We introduce two novel solution-processable electron acceptors based on an isomeric core of the much explored diketopyrrolopyrrole (DPP) moiety, namely pyrrolo[3,2-b]pyrrole-1,4-dione (IsoDPP). The newly designed and synthesized compounds, 6,6′-[(1,4

Pyrrole synthesis
Recent Literature An operationally simple, practical, and economical Paal-Knorr pyrrole condensation of 2,5-dimethoxytetrahydrofuran with various amines and sulfonamines in water in the presence of a catalytic amount of iron(III) chloride allows the synthesis of N-substituted pyrroles under very mild reaction conditions in good to excellent yields.

[PDF] Furan ring opening-pyrrole ring closure: a new …

A method of synthesis of pyrrolo[1,2-a][1,4]benzodiazepines is described. This method is based on the recyclization of N-(furfuryl)anthranilamides under treatment with an aq. HCl/AcOH system and allows one to form both diazepine and pyrrole rings in one step. The reaction proceeds via furan ring opening into a diketone moiety followed by consecutive interaction of the NH(2)-group with both
