, (2020/07/28)
The invention discloses propargyl-containing xylose and a preparation method thereof. The method comprises the following steps: using D-xylose as a raw material, carrying out full acetyl protection onthe D-xylose, introducing p-nitrophenoxy into a first position of an obtained compound, and removing acetyl to obtain a compound A; introducing tert-butyl dimethyl into the position 2, the position 3or the position 4 of the obtained compound A to obtain a compound B, a compound C and a compound D, and separating the compound B, the compound C and the compound D; and respectively carrying out acetyl protection on hydroxyl groups of the compound B, the compound C and the compound D, then removing the tert-butyl dimethyl, and respectively introducing propargyl into the position 2, the position3 and the position 4 to obtain the propargyl-containing xylose. According to the method disclosed by the invention, the propargyl is selectively connected to xylose for the first time by using a method for carrying out occupying by using tert-butyl dimethyl (TBS), so that a platform is provided for subsequent connection of the xylose to protein or amino acid, and a foundation is laid for biological research in the future.

Di-O-acetates and mono-O-acetates of 4-nitrophenyl β-D-xylopyranoside were prepared by use of lipase PS-30. Polarity of organic solvents and reaction time affected the regioselectivity of the di-O-acetylation as well as the yields of monoacetates. The kin
