Structural motifs in acetoacetanilides: The effect of a fluorine substituent

The structures of three fluoro-substituted acetoacetanilides were discussed. A planar structure with intramolecular hydrogen bonding was observed when the F atom was in ortho position of the aromatic ring, and a twisted structure with intermolecular hydrogen bonding was observed when the F atom was in meta or para positions. Fluorine appeared to mimic the steric effect of a large substituent which was attributed to high electronegativity.

A photoinduced pericyclic cascade reaction has been developed to afford oxabicyclo[4.2.0]octenes. Mechanistic studies show that this reaction undergoes [2 + 2]-photocycloaddition, base-promoted elimination, retro-4π-electrocyclization, [1,5]-H shift, and

The synthesis of novel hybrids, namely, phenothiazine and amide-ornamented nitrogen heterocycles (25-34) has been accomplished utilizing a multi-step synthetic protocol and the structures have been established based on physical and spectral techniques. Of these, the hybrids possessing meta-nitro (26), para-fluoro (28), meta- and para-methyl (31), ortho-bromo (33) and ortho- and para-dimethyl (34) phenyl carboxamide scaffolds exhibited superior anti-inflammatory profiles over the standard diclofenac sodium. A hybrid integrated with a para-fluorophenyl carboxamide moiety (28) showed the highest DPPH radical scavenging activity among the chemical entities synthesized. Furthermore, the results of anticancer evaluations implied that the hybrid tethered with a phenyl carboxamide structural unit (29) exerted superior activity when compared with other hybrids against the pancreatic cancer cells SW1990 and AsPC1. Molecular docking between the hybrid 29 and B-cell lymphoma 2 reflects its appreciable binding affinity (-8.84 kcal mol-1). The results revealed that these chemical entities can serve as potent biological agents and/or efficient intermediates for the construction of potent biological agents.
