aldehydes with methyl 11-bromoundecanoate (I) by the Wittig reaction. To obtain compound (I) from methyl undeca-2E,5E,10-trienoate or methyl undeca-10-enoate we used hydroboration according to Brown followed by hydrogenation and bromination of the alcohol obtained. The advantage of this method is the use as starting materials of esters of unsaturated acids readily obtained by the homogeneous catalytic co-oligomerization
已经开发了合成许多鳞翅目(Argyrotaenia velutinana、Mamestra configurata 和 Lycorea ceres)引诱剂的新途径。这些物质是具有顺式构型的烯醇的乙酸酯:分别为十四烷-11-烯-1-醇、十六烷-11-烯-1-醇和十八烷-11-烯-1-醇。所得物质的常数与文献中给出的常数完全一致。该方法基于通过 Wittig 反应将 C3、C5 和 C7 醛与 11-溴十一酸甲酯 (I) 偶联。为了从十一碳-2E,5E,10-三烯酸甲酯或十一碳-10-烯酸甲酯获得化合物(I),我们根据Brown使用硼氢化,然后对所得醇进行氢化和溴化。
