(−)-Yellow scale pheromone 1 has been synthesized by the route via [3,3]sigmatropic ring expansion of the 8-membered thionocarbonate 3 containing a diene moiety. The key Z-10-membered intermediate 2 was exclusively synthesized by a one-pot conversion from a chiral aldehyde (+)-4 and a dienyliodide 14.
(-)-黄色信息素1是通过含有二烯部分的8元硫代碳酸酯3的[3,3]σ环扩环的途径合成的。关键的Z-10-元中间体2仅通过一锅转化由手性醛(+)- 4和二烯基碘14合成。
