In the title compound, C(26)H(18)Br(2)O(4), the two 4-bromo-benzoyl groups at the 1- and 8-positions of the naphthalene ring system are anti to each other. The dihedral angle between the two benzene rings is 50.92 (14)°. The dihedral angles between the two benzene rings and the naphthalene ring system are 70.18 (11) and 74.98 (12)°. A weak inter-molecular C-H⋯O hydrogen bond exists between the methyl group and the carbonyl O atom.

Synthesis of naphthalene derivatives via nitrogen-to-carbon transmutation of isoquinolines.

Heteroarene skeletal editing is gaining popularity in synthetic chemistry. Transmuting single atoms generates molecules that have distinctly varied properties, thereby fostering potent molecular exchanges that can be extensively used to synthesize functional molecules. Herein, we present a convenient protocol for nitrogen-carbon single-atom transmutations in isoquinolines, which is inspired by the Wittig reaction and enables easy access to substituted naphthalene derivatives.

Antileishmanial and Antitrypanosomal Trends of Synthetic Tetralone Derivatives.

Leishmaniasis and trypanosomiasis are parasitic diseases that are closely linked to poverty, pose significant local burdens, and are common in tropical and subtropical regions. Various synthetic tetralone derivatives were studied as potential scaffolds for antileishmanial and antitrypanosomal activities. The compounds were studied for their effectiveness against multiple kinetoplastid protozoan pathogens: Leishmania major, Leishmania mexicana, and bloodstream trypomastigotes of Trypanosoma brucei brucei.

ConspectusSkeletal editing, which involves adding, deleting, or substituting single or multiple atoms within ring systems, has emerged as a transformative approach in modern synthetic chemistry. This innovative strategy addresses the ever-present demand for developing new drugs and advanced materials by enabling precise modifications of molecular frameworks without disrupting essential functional complexities. Ideally performed at late stages of synthesis, skeletal editing minimizes the need for the cost- and labor-intensive processes often associated with synthesis, thus accelerating the discovery and optimization of complex molecular architectures.

Pentalene (C8H6) and NN- and BB-bridged heterocyclic analogues (BN)4H6, derived by replacement of CC pairs with BN, are taken as  paradigms for tuning of ring-current (anti)aromaticity by variation of π charge, electronegativity and substitution pattern.  Ab initio calculation of maps for the π current density induced in these model systems by a perpendicular external magnetic field exhibits the full range of tropicity, from diatropic aromatic to nonaromatic to paratropic antiaromatic, with a ready rationalisation in terms of an orbital model.  Further calculations on systems of varying charge in which these motifs are embedded in extended PAH systems with naphthalene and phenanthrene 'clamps' show promise for switching between current patterns and related  opto-electronic properties.
