Sulfolane from Batzella

A sulfone (636) is a minor constituent of the Mediterranean sponge Anchinoe tenacior [502]. Sulfolane (637), a familiar industrial chemical, was isolated from a mixture of the sponge Batzella sp. and a Lissoclinum tunicate from Victoria, Australia [503]. It is possibly an absorbed compound rather than a natural product [12]. 

Very simple sulfones have also been isolated from marine organisms. The isolation of sulfolane (290) from the sponge/tunicate composite Batzella spJLissoclinum sp. was the first report, either terrestrial or marine, of this compound as a natural product [213]. The pyrogallol Phenol B (291), obtained from the red alga Grateloupia filicina, was...
