Structure and synthesis of the natural heptachloro-1′-methyl-1,2′-bipyrrole (Q1)
Which organism produces it? The natural product Q1 is 64 % chlorine and every third atom is a halogen, but the source of Q1 is unknown. Synthetic Q1, made for the first time, has identical chromatographic and spectroscopic properties to those of Q1 extracted from environmental samples.

Synthesis of 1,2′- and 1,3′-bipyrroles from 2- and 3-nitropyrroles
1,2′- and 1,3′-Bipyrroles, which are attractive precursors for the synthesis of bipyrrole-based natural products, are synthesized in one-pot from 2- and 3-nitropyrroles by a sequential nitro group reduction-Paal-Knorr pyrrole synthesis.
