Nuclear Magnetic Resonance Studies of Cytochalasin E and Its Decomposition Product

The proton and carbon-13 nuclear magnetic resonance signals of cytochalasin E (1) were assigned with the aid of 1H-1H, 1H-13C and 1H-13C long-range chemical shift correlation spectroscopy spectra, and the structure of the decomposition product (2) generated under neutral conditions was determined.
