Phytophthera Of ¦Á1 Sex Pheromone Synthesis Research

Insect sex pheromones are designed as the trace of chemical substance which are excreted by insect and influences the behavior or development of others of the same species.Phytophthora (Phytophthora sojae) is a class of non-egg algae fungus pathogens,can induce important large-scale destruction of crops world-class. The Phythopheraα1 (3,7,11,15) - tetramethyl -4 - oxo - (1,11,16) - triol with four chiral methyl, the absolute configuration was not determined, so it's absolute configuration would be synthesized and text the biological activity in this article . Chiral (R) -3 - methyl-γ-butyrolactone and 3 - hydroxy -5 - methyl caprolactone are industrial waste, as the available material. Selected ( 3R,7S,11R,15R) - Phythophera 1 to synthesize, (R) -3 - methyl-γ-butyrolactone as the starting material synthetic fragment 04 and fragment 10, fragment 04, and 10 fragments generated by nucleophilic addition of 11, for the Phytophthora homone's left fragment; again with 3 - hydroxy -5 - methyl caprolactone synthetic fragment 35 as the starting material, to commercial reagent 3 - methyl -3 - en -1– butanol synthesized fragment 38, fragments of 35 and 38 Synthesis of Phytophthora link right half of the homone, the 39 fragments. 11,39 shall Phytophthora homone (3R, 7S, 11R, 15R) - 4-methyl -4 - oxo - (1,11,16) - Calcitriol main fragments.
