Synthesis of Phenylseleno Sugars from Epoxides and of α,β‐Unsaturated Carbonyl Derivatives for the Study of Their Insecticidal Activity

Abstract

This work reports the synthesis of sugar epoxides and their derivatives obtained by reaction with the dianion of phenyl selenoacetic acid. Approaches to the introduction of α,β‐unsaturated carbonyl units in pyranoid systems were investigated. Preparation of a protected D‐glycero‐hex‐3‐enepyranosid‐2‐ulose and of a D‐erythro‐hex‐2‐enono‐1,5‐lactone is described. Some of the synthesized compounds possess insecticidal activity against fruit flies, house flies, and white flies.
