Abstract
The invention belongs to the technical field of organic chemistry, in particular relating to a preparation method for an Arabian glycal. The method adds 1-bromination acetylation arabinose into a reaction system which comprises zinc powder, sodium dihydrogen phosphate, acetone and water, and D-acetylation Arabian glycal is generated through the reaction; after the generated D-acetylation Arabian glycal is dissolved in methanol, potassium carbonate is added into the solution, and D-Arabian glycal is generated through the reaction. The preparation method for the Arabian glycal has the advantages of simple operation, high yield, short reaction time, low cost, few three wastes, little environmental pollution and easy industrialization.
Description
A kind of method for preparing arabinose technical field The invention belongs to the technical field of organic chemistry, and in particular relates to a preparation method of arabinose. Background technique In the synthesis of organic compounds and drugs, arabinose and glucal are very important raw materials, but the high price in the market greatly limits their application in various aspects. At present, there are many reports on the preparation methods of acetylated glucal sugar, and more than a dozen kinds can be retrieved, and new process reports are constantly being reported. But there are few reports on the preparation of acetylated arabinose and arabinose. By searching, we found out that the preparation method of acetylated xylose, which is the isomer of acetylated arabinose, is mainly to obtain the target from a substituent, such as: (1) Tetrahedron Letters 2006, 47(34), 6117-6120 (2) Synthesis 1989, 10, 758-759 (3) J.Org.Chem.1995, 60, 7055-7057 T...
