  • SYNTHESIS OF SUBSTITUTED FURANS
    Publication number: 20230150962
    Abstract: A method is provided of preparing a compound of formula II: where: R1 and R2 are independently selected from —CH2OR?, —CHO, —COOR? and —H, provided that R1 and R2 are not both —H; and R? is selected from —H and C1-6 hydrocarbyl groups, from a compound of formula I: the compounds of formulas I and II being optionally in the form of a salt. The method comprises dehydrating the compound of formula I at: a pH in the range of from 0 to 6 or 8 to 11.5; and a temperature in the range of from 10 to 80° C. The method is particularly useful for synthesizing substituted furans from compounds derived from sugars.

  • PURIFYING AND POLYMERIZING 3'-BLOCKED NUCLEOTIDES
    Publication number: 20220389500
    Abstract: A method for purifying nucleotides is provided, that includes preparing a solution comprising (a) 3?-blocked nucleotides, (b) 3?-OH nucleotides, (c) a polishing polymerase, and (d) a template. The polishing polymerase and the template are used to selectively polymerize the 3?-OH nucleotides and thus reduce a concentration in the solution of the 3?-OH nucleotides relative to the 3?-blocked nucleotides.
