Abstract

YAMAGUCHI'S studies on the pigments of a Japanese sea sponge, Renziera japonica, led to the discovery of a novel class of natural carotenoids containing aryl end-groups. Renieratene, isorenieratene, and renierapurpurin were shown to have structures (Vc),(Va), and (Vb), re~ pectively,~.~ and these structures were confirmed by syntheses 993 (albeit in low yields) from oct-4-ene-2, 7-dione and aryl analogues of@-i~ none,~*~ following a ...
