Natural free carboxylic acids from the hadromerid sponge Diacarnus levii (Kelly-Borges and Vacelet) were esterified to yield the new cyclic norditerpene peroxides ent-muqubilin benzyl ester (= (αR,3S,6R)-α,6-dimethyl-6-[(E)-4-methyl-6-(2,6,6-trimethyl-cyclohex-1-en-1-yl)hex-3-enyl]-1,2-dioxan-3-acetic acid benzyl ester; 6, diacarnoate B methyl ester(= (αS,3R,6R)-α,6-dimethyl-6-2-(4aS,8aS)-3,4,4a,5
从hadromerid海绵天然游离羧酸Diacarnus LEVII(凯利-博尔赫斯和Vacelet)进行酯化,以产生新的环状norditerpene过氧化物ENT -muqubilin苄酯(=(α [R,3小号,6 - [R)-α,6-二甲基6-[((E))-4-甲基-6-(2,6,6-三甲基-环己-1-烯-1-基)己-3-烯基] -1,2-二恶烷-3-乙酸苄基酯; 6,壬烯酸酯B甲酯(=(αS,3 R,6 R)-α,6-二甲基-6- 2-(4a S,8a S)-3,4,4a,5,6, 7,8,8a-八氢-3-氧代-2,5,5,8a-四甲基萘-1-基)乙基} -1,2-二恶烷-3-乙酸甲酯; 9)和脱氧二壬酸酯B苄基酯(=(αS,3 R,6 R)-α,6-二甲基-6- 2-[((4a S,8a S)-3,4,4a,5,6, 7,8,8a-八氢-2,5,5,8a-四甲基-1-萘基]乙基}
