Twenty nine 3,5-dibromotyrosine derivatives were isolated from the ethanol extract of the marine sponge Aplysina sp. (South China Sea) including the earlier unknown compounds, in particular, p-hydroxycyclohexadienone and p-hydroxycyclohexenone ketals. The isolated enones, dienones, and ketals can be transformation products of aeroplysinin-1 in the course of its reactions with water and alcohols.

Low temperature addition of functionalized alkyllithium reagents to p-benzoquinones produces 4-alkyl-4-hydroxycyclohexa-2,5-dienones, and reaction of excess of the reagents with quinones yields 1,4-dialkylcyclohexa-2,5-diene-1,4-diols.With 4-acetoxy-, 4-h
