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.

Two dibromo nitriles, (1' R,5' S,6' S)-2-(3',5'-dibromo-1',6'-dihydroxy-4'-oxocyclohex-2'-enyl)acetonitrile (5) and the (1' R,5' R,6' S) epimer (6), possessing antimicrobial activity, have been isolated from the sponge Aplysina laevis (Carter).Cometabolites (+)-aeroplysinin-1 (1) and the dibromo ketone (2) were also identified.Structures (5) and (6) were assigned on the basis of spectroscopic evidence and synthesis from (1).
ADDITION OF FUNCTIONALIZED ORGANOLITHIUM REAGENTS TO p-BENZOQUINONES AND CYCLOHEXADIENONES: SYNTHESIS OF FUNCTIONALIZED CYCLOHEXADIENONES, DIENOLS AND DIENEDIOLS

, p. 131 - 134 (2007/10/02)
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
