Ethyl 4-anilino-3-nitrobenzoate [PDF]
Acta Crystallographica Section E Structure Reports Online, 2008 In the title compound, C(15)H(14)N(2)O(4), the aromatic rings are oriented at a dihedral angle of 78.33 (3)°. An intra-molecular N-H⋯O hydrogen bond results in a non-planar six-membered ring with a flattened-boat conformation. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules.

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 8, Page 1529-1540, August 2026.ABSTRACT BorF is a short‐chain flavin reductase from a desert soil bacterium that uses NADH to reduce FAD to FADH2, which is used by the tryptophan‐6‐halogenase BorH to chlorinate tryptophan in the biosynthetic pathway of borregomycin A. The X‐ray crystal structure of BorF bound to FAD was solved to 2.37 Å by molecular replacement.

3,4-Diaminopyridinium 4-nitrobenzoate–4-nitrobenzoic acid (1/1)
Acta Crystallographica Section E, 2009 In the title compound, C5H8N3+·C7H4NO4−·C7H5NO4, the non-H atoms of the 3,4-diaminopyridinium cation are coplanar, with a maximum deviation of 0.022 (1) Å. The carboxylate and nitro groups of the 4-nitrobenzoate anion are twisted out of the attached ring planes by dihedral angles of 15.89& ...

Angewandte Chemie, Volume 138, Issue 2, 9 January 2026.Twin natural products. This manuscript describes a concise biomimetic synthesis of twin abeo‐steroids bufogargarizins A and B with an unusual [7.5.6.5] and [5.7.6.5] skeletons in 19 steps (LLS). The described synthetic approach features the application of a bioinspired regiodivergent intramolecular aldol addition reaction and a selective singlet oxygen‐

Elimination of acrolein from cider by addition of sulphur dioxide
Journal of Chemical Technology &Biotechnology, Volume 101, Issue 6, Page 1254-1262, June 2026.Abstract BACKGROUND Acrolein is a toxic substance that sometimes appears in ciders, imparting an unpleasant taste and odour, which spoils the beverage entirely. Based on the reaction between acrolein and sulphur dioxide to form adducts, some oenologists of the Basque Country and Navarre (Northern Spain) use sulphur dioxide to remove acrolein.
