The structures of phenochalasins A and B were elucidated by spectroscopic s
tudies including various NMR measurements. Phenochalasins A and B have the
cytochalasan skeleton of the 21,23-dioxa, 17,22-dione moiety containing uni
que phenyl and O-methyl phenyl residues at the C-10 position, respectively.
