Method for synthesizing glassine

The invention relates to a method for synthesizing a glassine. The method comprises the following steps: reacting (2R, 3S, 4S)-2, 3, 4-tribenzyloxy glutaraldehyde with acetone to synthesize a key intermediate (E)-(2R, 3S, 4S)-2, 3, 4-tribenzyloxy pentyl-6-acetyl hexane-5-olefine aldehyde, then catalyzing (E)-(2R, 3S, 4S)-2, 3, 4-tribenzyloxy pentyl-6-acetyl hexane-5-olefine aldehyde with Lewis acid to sequentially carry out a nucleophilic addition and a 1, 4-Michael addition reactions, obtaining benzyl-protected Pro-Xylane 1-((2S, 3S, 4S, 5R)-3, 4, 5-tri(benzyloxy) tetrahydro-2H-pyran-2-yl)propan-2-ol, and finally, carrying out catalytic hydrogenation by using palladium carbon to remove benzyl, so as to obtain Pro-XylaneTM (2S, 3R, 4S, 5R)-2-(2-hydroxypropyl) tetrahydro-2H-pyran-3, 4, 5-triol. The method is high in reaction yield, the obtained product is high in purity, and the method has huge application value.

Method for synthesizing glassine by one-pot method

The invention discloses a method for synthesizing a bose by a one-pot method, which comprises the following step of: synthesizing the bose by the one-pot method under the action of a catalyst and a reducing agent by taking xylose and acetoacetate substances as raw materials in the presence of an organic solvent. The method has the advantages of easily available catalyst and reducing agent, low cost and high yield, and is suitable for industrial production.
