一个简捷、高效合成松叶蜂性信息素的方法
A Concise Synthesis of the Sex Pheromones of Pine Sawflies
【摘要】 以从甾体皂甙元降解的废弃物获取的(4R)-甲基-5-溴戊酸甲酯(4)为起始原料,通过4与正庚基溴化镁选择性的偶联反应,经关键合成中间体(4S)-甲基溴代十二烷(7)分别以52%和49%的总收率合成了松叶蜂性信息素(2S,3S,7S)-3,7-二甲基十五-2-醇乙酸酯(2)和丙酸酯(3).
【Abstract】 Starting from methyl (R)-5-bromo-4-methylpentanoate (4) obtained from the waste in the degra-dation of steroid sapogenin, (2S,3S,7S)-3,7-dimethylpentadecan-2-yl acetate (2) and propionate (3) were synthesized via the coupling reaction of 4 with heptyl Grignard in 52% and 49% overall yields respectively.
