Conventional and Unconventional Intramolecular Hydrogen Bonding in some Beta-diketones

  title={Conventional and Unconventional Intramolecular Hydrogen Bonding in some Beta-diketones},
  author={Vahidreza Darugar and Mohammad Vakili and Raheleh Afzali and Sayyed Faramarz Tayyari},
This study presents our view of unconventional and conventional intramolecular hydrogen bonds (HBs) for some beta-diketones theoretically and experimentally. According to our results, the groups such as Phenyl and t-But in beta positions increase and CF3 group decrease IHB strength, respectively. For better understanding of the substitution effects, the compounds with similar and different substitutions compared to each other experimentally and theoretically. Comparison between theoretical and… Expand

Synthesis, computational study and cytotoxicity of 4-hydroxycoumarin-derived imines/enamines
The 4-hydroxybenzyl derivative 3k was found to be the most potent cytotoxic agent with no selectivity, similar to doxorubicin, however, the 4-chlorobenzyl analog 3o could be considered as an equipotent compound respect toDoxorUBicin with higher selectivity. Expand
