## Abstract The ^13^C shifts of 16α‐ and 16β‐substituted derivatives of quebrachamine, 14,15‐dehydroquebrachamine, cleavamine, 15,20α‐dihydrocleavamine and 15,20β‐dihydrocleavamine are determined and correlated with possible conformations of these tetracycles. The method of analysis of the C(16) co
The 13C-NMR spectra of 4-methacryloyloxyethyl trimellitate anhydride (4-META ; 1) and its hydrate (4-MET ; 2) have been completely assigned using a combination of 2D NMR experiments (13C-1H HETCOR and HMBC) and a heteronuclear NOE experiment.
