acetal 2-ethyl-1,5-dimethyl-6,8-dioxabicyclo[3.2.1]octane (1), identified as an aggregation pheromone of males of the beech bark beetle, Taphrorychus bicolor, was determined by unambiguous synthesis and NMR experiments. The syntheses of the racemates of both diastereomers and of optically pure samples are described. The natural product proved to show (1S,2R,5R) configuration.
新的双环缩醛2-乙基-1,5-二甲基-6,8-二氧杂双环的绝对构型[3.2.1]辛烷(1),确定为山毛榉小蠹,雄性的聚集信息素Taphrorychus双色,是通过明确的合成和NMR实验确定。描述了非对映异构体和光学纯样品的外消旋体的合成。天然产物证明显示(1 S,2 R,5 R)构型。
