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).

关键词: 松叶蜂性信息素, (4R)-甲基-5-溴戊酸甲酯, 偶联反应

Starting from methyl (R)-5-bromo-4-methylpentanoate (4) obtained from the waste in the degradation 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.

Key words: methyl (R)-5-bromo-4-methylpentanoate, coupling reaction, sex pheromone of Pine sawfly
