The first total synthesis of two marine animated hydroxynaphthazarins, echinamines A (3-amino-7-ethyl-2,5,6,8-tetrahydroxy-1,4-naphthoquinone) and B (2-amino-7-ethyl-3,5,6,8-tetrahydroxy-1,4-naphthoquinone), produced by the sea urchin Scaphechinus mirabil

Catalytic hydrogenation of the benzotripyranone 3 yields the hexahydrobenzotripyrans 5 and 6, while ring closure reactions of the 1,2,4-benzenetriyltris(3-oxypropionic acid) 16c and catalytic hydrogenation lead to the less symmetric isomers 21 and 12.
