Six bonds are formed on one pot to give 1,4‐dihydropyrrole[3,2‐b]pyrroles in an operationally simple reaction that is described by Daniel Gryko and co‐workers in their Full Paper on page 411 ff. The target compounds are formed in a domino process from aldehydes, primary amines, and butane‐2,3‐dione. Such fused pyrroles have interesting optical properties but are among the least studied heteropentalenes because they have previously been difficult to synthesize. One of several potential applications of 1,4‐dihydropyrrole[3,2‐ b ]pyrroles is demonstrated in a fluorescent cell‐imaging experiment.
