Abstract

Chinese bittersweet, Celastrus angulatus Max., is a widely distributed plant and is used as a traditional insecticide in China. Celangulin V (CA‐V), one of the main insecticidal ingredients from the plant, has special insecticidal mechanism. A synthesized compound, 6β‐propoxycelangulin V, exhibits more remarkable insecticidal activity against insect pests. In this study, the synthesis of a labeled version of a CA‐V analog, 6β‐([1‐^14^C]propoxy)celangulin V, was accomplished from 1‐[1‐^14^C]propanol and CA‐V in two steps with the chemical and radiochemical purities of 98.7 and 99.9%, respectively. The labeled compound can be used as a radiotracer to study the mechanism of action of CA‐V analogs. Copyright © 2008 John Wiley & Sons, Ltd.
