Synthesis of the Sex Pheromones of the Pine Caterpillar, Dendrolimus punctatus (Walker)
The pine caterpillar, Dendrolimus punctatus (Walker), is Shorts a notorious forest pest.An efficient and convenient synthesis of the sex pheromones of this pest has been achieved.In our synthetic approach, a Wittig coupling of an aldehyde with an ester-bearing phosphonium salt was used to construct the Z-alkene, whereas the E-alkene was prepared vi
