摘要
欧洲榆小蠹原产欧洲榆树生长区，美国、加拿大及非洲北部也有分布，其成虫及幼虫蛀食榆树皮，并能传播榆疫病，从而影响榆树生长．Ｐｅａｒｃｅ等分离出其聚集信息素并鉴定其分子结构为（—）４甲基３庚醇（１）［１］，Ｍｏｒｉ等研究结果确定出其天然产物构型为...
R,4R)4Methyl3heptanol, the enatiomer of aggregation pheromone of the smaller European elm bark beetle(Scolytus Multistrialus), was stereoselectively synthesized using Nbornane2,10sultam as a chiral auxiliary. The two asymmetric carbon atoms of the target product were achieved by employing asymmetric synaldolization of Npropionylbornane2,10sultam( 3 ) with propylaldehyde. The enantiomeric excess of (3R,4R)4methyl3heptanol prepared by this route is about 943%.
