In an approach to opioid receptor ligands,diazabicyclononanones were prepared in a double Petrenko-Kritschenko reaction. Diester 76, in the presence of methylamine and aryl aldehydes, was converted to piperidone 77. This was immediately resubmitted to the reaction conditions however, in this iteration formaldehyde replaced the aryl aldehyde component. The outcome of this reaction produced 78 which was further investigated for its use in rheumatoid arthritis. 

The g-tensor principal values of radical cations were shown to be sensitive to the presence or absence of dimer- and multimer-stacked structures (Petrenko et al. 2005). If face-to-face dimer structures occur (see Scheme 9.7), then a large change occurs in the gyy component compared to the monomer structure. DFT calculations confirm this behavior and permitted an interpretation of the EPR measurements of the principal g-tensor components of the chlorophyll dimers with stacked structures like the P 00 special dimer pair cation radical and the P700 special dimer pair triplet radical in photosystem I. Thus dimers that occur for radical cations can be deduced by monitoring the gyy component.
