Abstract

Furthermore, it can isolated from a sponge "Reniera japonica", it has previously been shown from the be inferred from the analogy with another terminal group, that the ring may be a result of the chromic acid oxidation, by benzene ring. which crocetin dialdehyde has been iso- lated besides other products, that renie- ratene is a derivative of tetramethyl- octadeca-nonaene2).

As isorenieral is also one of the degradation products of renieratene, it is clear that renieratene can be expressed by the partial formula III.
