Abstract: Abstract The unprecedently rearranged 6/5/8/6/5 pentacyclic monoterpenoid indole alkaloid voafriamidine from Voacanga africana contains an uncommon N-acyl amidine structural motif that forms a unique 2,4-diazatricycle-[6,5,11,8,03,7] tetradecane skeleton. Despite the lack of proper NMR correlations for… read more here.
