| titleOfInvention | A kind of method preparing 2-deoxidation-L-ribose |
| abstract | The invention discloses a kind of method preparing 2-deoxidation-L-ribose.Be initial feed with L-arabinose, utilize acetyl bromide to obtain the triacetylated pectinose of Beta-bromo-L-for protecting group and brominated reagent; Then triacetylated for Beta-bromo-L-pectinose is joined in the reaction system containing zinc powder, sodium pyrosulfate, copper sulfate, water, room temperature reaction, obtains through dilution, filtration, washing, concentrating under reduced pressure rectifying the acetylize L-arabinose alkene that purity is greater than 99% subsequently; Subsequently acetylize L-arabinose alkene is dissolved in ethanol, adds salt of wormwood reaction, generate intermediate L-arabinose alkene; Under sulfoalkyl pyrazine vitriol-long-chain polyolefine sulfonate resin composite catalyzing effect, there is hydration addition and obtain target product 2-deoxidation-L-ribose in L-arabinose alkene.The present invention is raw materials used is conventional reagent, simultaneous reactions condition is gentleer, working method and aftertreatment technology simple, product yield and purity all more satisfactory. |
