Abstract

The first total synthesis of mirabiquinone A (2,3,5,6,8,10,11,13-octahydroxy-7-methyl-1H-dibenzo[b,h]xanthene-1,4,9,12(7H)-tetraone) produced by the sea urchin Scaphechinus mirabilis is described. This was achieved by cyclization of 6,6′-ethylidenebis(7-hydroxy-2,3-dimethoxynaphthazarin) or its mono- or dimethoxy derivatives and functional group deprotection. The synthesis of methyl analogues of mirabiquinone A is also described.
