10-Deacetylbaccatin III

C29H36O10

PROCEDURE

实验过程

in a polar solvent, reaction the resultant solution with a base at a temperature of 20-50° C. for a time period in the range of 20-40 hours, and isolating 7-xylosyl-10-deacetylbaccatin III, dissolving the 7-xylosyl-10-deacetylbaccatin III in a polar solvent, reacting the resultant solution with a periodate at 20-40° C. for a time period in the range of 20-40 hours to cleave the diol system of the xyloside into dialdehyde, treating the generated dialdehyde in an organic acid medium with salts of amine at 0-40° C. for 12-18 hours and isolating 10-deacetylbaccatin III of formula 1.
