Two new tetrahydropyrans have been isolated from the sponge Haliclona sp. From chemical and spectroscopic evidence they are shown to be (1′R, 2S, 2″E, 5R, 6R)-2-(1′-bromethyl)-2,5-dimethyl-6-(penta-2″,4″-dienyl)-tetrahydropyran and (1′R, 2S, 5R, 6R)-2-(1′-bromoethyl)-2,5-dimethyl-6-(pent-4″-enyl)-tetrahydropyran.
从海绵Haliclona sp。分离出了两个新的四氢吡喃。从化学和光谱学证据来看,它们被证明是(1'R,2S,2″ E,5R,6R)-2-(1'-溴甲基)-2,5-二甲基-6-(penta-2″,4 ″-二烯基)-四氢吡喃和(1'R,2S,5R,6R)-2-(1'-溴乙基)-2,5-二甲基-6-(戊-4″-烯基)-四氢吡喃。
