Abstract
Several skeletal and oxidative transformations of 11-deoxyglycyrrhetic acid were carried out to produce A-nor-derivatives. Signals for protons and C atoms in the PMR and 13C NMR spectra of the A-nor-derivatives were assigned using high-resolution 1H (400 MHz) and 13C (125 MHz) NMR spectroscopy.
