Synthesis of Phenylseleno Sugars from Epoxides and of α,β‐Unsaturated Carbonyl Derivatives for the Study of Their Insecticidal Activity
摘要:
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 alpha,beta-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.
