N2  - From the deep violet, encrusting marine sponge Chelonaplysilla violacea, two rearranged spongian diterpenes, aplyviolene, (1R*,1&#8242;S*,3?aR*,5R*,6R*,8R*,8&#8242;aS*)-3-oxo-8-(1&#8242;,4&#8242;,4&#8242;-trimethyl-8&#8242;-methylenedecahydroazulen-1&#8242;-yl)-2,7-dioxabicyclo[3.2.1]oct-6-yl acetate (1), the acetoxy derivative, aplyviolacene (2), (5R*,8S*,9S*,10R*,13S*,14R* ,15S*,16R*)-spongian-15,16-diyl diacetate (3) and (5R*,8S*,9S*,10R*,13S*,14R*)-spongian-16-one (4) were isolated. The structures were determined by spectroscopic methods, and the structure of aplyviolene was confirmed by a single-crystal X-ray determination. The crystal structure was refined to a residual of 0.036 for 1125 independent observed reflections. The crystals were orthorhombic, space group P212121 with a 8.098(1), b 11.628(1), c 21.774(3)&#506;.
