Aerothionin, a tetrabromo derivative, has been isolated from sponges Aplysina aerophoba and Verongia thiona the proposed structure is 24 (46). The oxime 25 was formed by treatment of aerothionin with dilute alkali. The relative positions of the aromatic substituents in 25 were established by cleavage in hot 6 N HC1 to give 26 and a lactone subsequently converted by methylation to 27. The tetramethyl derivative of 25 was hydrolyzed to form...
