efficient synthesis of a naturally occurring acetylenic alcohol 15-methyltricosa-2,4-diyne-1,6-diol (strongylodiol-G) derived from marine sponge involving nine steps has been described. 1-Bromo-9-methyloctadecane (5) and hex-6-tetrahydropyranyloxyhex-2,4-diyn-1-al (9) which were initially synthesised separately starting from 1,8-octanediol (1) and propargyl alcohol (6), respectively, have been used as the
已经描述了衍生自海洋海绵的天然乙炔醇15-甲基三甲苯-2,4-二炔-1,6-二醇(强缩二醇-G)的第一全部有效合成,该合成涉及九个步骤。分别由1,8-辛二醇(1)和炔丙醇(6)分别开始合成的1-Bromo-9-甲基十八烷(5)和hex-6-四氢吡喃氧基己二-2,4-diyn-1-al(9)分别用作最终中间体以获得标题化合物。合成中的关键步骤包括使用酸性离子液体[bmim] HSO 4进行离子液体介导的1,8-辛二醇的溴化(1),8-溴辛烷-1-醇的四氢吡喃基化(2)。和使用超声波能量对hex-2,4-yn-1,6-二醇(7)进行单四氢吡喃基化。
