Abstract

magnified image

A series of novel title compounds have been designed and synthesized by a multi‐step reaction, the stereochemistry of the reaction was investigated, the structures of all compounds prepared have been confirmed by ^1^H NMR, IR, EI‐MS spectroscopy and elemental analysis. The crystal structures of cis 6b and trans 6b were determined by single crystal X‐ray diffraction. The results of preliminary bioassay indicate that some compounds possess a certain extent inhibition effect against aphides at the concentration of 250 ppm.
