The sponges Raspailia pumila and ramosa (Demospongiae, Tetractinomorpha, Axinellida) from the North-East Atlantic are shown to contain a series of novel long-chain enol ethers of glycerol where the enol ether CC bond is conjugated, in sequence, to both an acetylenic and an olefinic bond. Polar extracts give raspailynes hydroxylated at their (1Z5Z)-1,5-alkadien-3-ynyl chain, like raspailyne Al ( = (+)-(S)-3-[((1Z
来自东北大西洋的海绵Raspailia pumila和ramosa(Demospongiae,Tetractinomorpha,Axinellida)含有一系列新型的甘油长链烯醇醚,其中烯醇醚CC键依次键合到两个炔属上和烯键。极性提取物会产生在其(1 Z 5 Z)-1,5-alkadien-3-ynyl链上羟基化的拉斯帕林烯,如raspailyne Al(=(+)-(S)-3-[((1 Z,5 Z)- 16-羟基-十六烷-1,5-二烯-3-炔基氧基)-1,2-丙二醇;(+ 2)和异阿斯比林A(=(+)-3-[(((1 Z,5 Z)- 17-羟基八-癸基-1,5-二烯-3-炔基)氧基] -1,2- [丙二醇;(+)-3)。极性较小的提取物会产生3种不同类型的rapaspalynes,它们在链上没有被羟基化。第一种类型的Raspailynes在线性链中具有(1 Z,5 Z)-构型,例如raspailyne
