The ant substance (Z,E)-α-farnesene and its isomer (Z,Z)-α-farnesene have been synthesized in an overall yield of 34% in six stages from methyl cyclopropyl ketone and 6-methylhept-5-en-2-one via a Wittig condensation. A mixture of the corresponding (Z,E)-α-homofarnesene of ants and its (Z,Z) isomer were prepared in much poorer yield by the same method and incompletely characterized. The isomeric identification
从甲基环丙基酮和6-甲基庚基5-en-烯基化合物的六个阶段中,合成了蚂蚁物质(Z,E)-α-法呢烯及其异构体(Z,Z)-α-法呢烯,总收率为34%。通过Wittig缩合反应生成2个。通过相同的方法,以相对较差的收率制备了相应的蚂蚁的(Z,E)-α-法莫烯及其(Z,Z)异构体的混合物,并且未完全表征。证实了两种昆虫材料的同分异构鉴定。
