ABSTRACT Advances in Nuclear Magnetic Resonance (NMR) spectroscopy is a cornerstone structure elucidation of polycyclic 'cage' scaffolds. Due to the compactness these compounds, much overlap, as well unique through-space and bond NMR interactions are frequently observed. This review serves guide for future derivatives by providing some typical relevant aspects characteristic trends, substituent...

The Iberian Peninsula holds one of the richest myrmecofauna Mediterranean basin, but some regions such as Portugal remain comparatively undersampled. Although new unrecorded species have been regularly found and published during last two decades, sum is still far from approaching more than 300 known to occur in Peninsula.
