Abstract
Cynafogenin (1) contains two distinct ester groups, acetate and benzoate, located at C-11 and C-12, respectively. The positions of the ester linkages were determined by an application of the long-range selective proton decoupling (LSPD) technique. Further, the aromatic carbons of benzoate and the methyl carbons at C-18 and C-19 were assigned.
