O-demethylaseO-脱甲基酶
1.Moreover,Spinosad had obvious induction to the activity of carboxylesterase(CarE),glutathione-s-transferase(GSTs) and O-demethylase in tobacco beetle larvae,and also had certain effects on the kinetics constants,Vmax and Km,of carboxylesterase.89%～100%;同时,Spinosad对烟草甲幼虫体内的羧酸酯酶(CarE)、谷胱甘肽转移酶(GSTs)和O-脱甲基酶活性均有明显的诱导作用,并对羧酸酯酶的动力学常数Vmax和Km也有一定影响。
3)5'-O-(4,4'-Dimethoxytrityl)-2'-deoxyuridine5'-O-[双(4-甲氧基苯基)苄基]-2'-脱氧尿苷
4)O-methylationO-甲基化
1.2% was synthesized from 4-chlorophenol by acylation,Fries rearrangement,O-methylation,oxidation.以间氯苯酚为原料,经乙酰化、Fries重排、O-甲基化和氧化反应合成了2-甲氧基-4-氯苯甲酸,总收率54。
2.This paper aimed to design a new synthetic route:starting from phenols,via acylation,Fries rearrangement,O-methylation,oxidation,getting corresponding alkoxy benzodic acids.本课题提出一条合成安息香酸的新路线,该合成路线以酚类物质为原料,通过醋酐乙酰化,Fries重排,O-甲基化,次氯酸钠氧化反应将羧基引入苯环,从而合成烷氧基安息香酸系列。
