Plakortic acid

The cyclic peroxide system was constructed by photo-addition of 02 to the diene 25 in a total synthesis of plakortic acid derivatives isolated from a marine sponge <02OL485> and the key step in a synthesis of related marine products is an intramolecular Michael addition of a peroxy hemiacetal <02BMCL69>. [Pg.376]
