The absolute configuration of organic compounds bearing chiral quaternary carbons is determined by the crystalline sponge method.

Novel naphthalene-heterocycle hybrids were synthesized via tandem reactions of 3-formylchromone with different nucleophilic reagents. Various hybrids revealed potent antitumor and anti-inflammatory as well as promising antituberculosis activities.

The highly enantioselective cyclization of 3-alkenylindole via C-H activation has been established using Pd(OCOCF) in conjunction with the chiral spiro bis(isoxazoline) ligand (SPRIX). The presence of an N-allyl substituent on the substrate has a strong impact on both reactivity and selectivity, leading to tricyclic indole products (up to 96% ee) with a chiral quaternary carbon center.

This study reported the chemistry of 1,3,5-triazepines. Heterocyclic 1,3,5-triazepines are mono and fused cycles.

The versatile precursor 2-acetyl-4-allyl-1-hydroxy naphthalene was synthesized efficiently via Claisen rearrangement 2-acetyl-1-allyloxynaphthalene. The Claisen-Schmidt condensation of latter precursor afforded the corresponding chalcones which were exploited to synthesize a series of potential heterocycles such as pyrazoline, isoxazoline, benzocoumarin and benzoflavone. The synthesized products showed potent antioxidant and antimicrobial activities. Chalcone , naphthyl pyrazoline and hydroxycoumarin exhibited the highest activity as antioxidants. Their binding mode showed specialized recognition of hydroxycoumarin with the triad key amino acids at the active site of the oxidoreductase enzyme (PDB code 1DXO). 1-Hydroxynaphth-2-yl pyrazoline () revealed the highest efficacy against both Gram positive and negative bacterial species. molecular docking of pyrazoline endorsed its proper binding at the active site of the 2EX6 enzyme which explains its potent antibacterial activity in comparison with standard ampicillin.
