    • 3,4-Dihydroquinoxalin-2-ones: recent advances in synthesis and bioactivities 

      Kristoffersen, Tone; Hansen, Jørn H. (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-04-26)
      A summary of recent synthesis approaches to 3,4-dihydroquinoxaline-2-ones is discussed herein along with highlights of biological activity. The synthetic approaches include access to enantiopure heterocycles from chiral pool amino acids via coupling/cyclization, Michael addition/cyclization cascades, 3,3-disubstituted systems from multicomponent couplings, Bargellini reaction or photochemical ...

    • Cryptophanes for Methane and Xenon Encapsulation: A Comparative Density Functional Theory Study of Binding Properties and NMR Chemical Shifts 

      Demissie, Taye Beyene; Ruud, Kenneth; Hansen, Jørn H. (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-27)
      The host-guest chemistry of cryptophanes is an active research area because of its applications in sensor design, targeting small molecules and atoms in environmental and medical sciences. As such, the computational prediction of binding energies and nuclear magnetic resonance (NMR) properties of different cryptophane complexes are of interest to both theoreticians and experimentalists ...
