TL;DR: In this paper, a kind of preparation method of o-nitrophenyl galactoside was provided, which consisted of tetra-acetylated bromo-galactose, o-NP, sodium hydroxide and Tetrabutyl amonium bromide reacting by heating in water and methylene dichloride.
Abstract: The invention provides a kind of preparation method of o-nitrophenyl galactoside, comprise: by tetra-acetylated bromo-galactose, o-NP, sodium hydroxide and Tetrabutyl amonium bromide reacting by heating in water and methylene dichloride, obtain tetra-acetylated o-nitrophenyl galactoside; Tetra-acetylated o-nitrophenyl galactoside is carried out deacetylated, obtains o-nitrophenyl galactoside.Tetra-acetylated bromo-galactose and o-NP react by the present invention in the system of Tetrabutyl amonium bromide and sodium hydroxide; the existence of Tetrabutyl amonium bromide and sodium hydroxide can make the reaction of o-NP and tetra-acetylated bromo-galactose more thorough; shorten the reaction times, improve reaction yield.
