  • INDUSTRIAL SYNTHESIS OF SERINOL
    Publication number: 20240199530
    Abstract: The present invention is related to the synthesis of 4-hydroxymethyl-2-oxazolidinone (serinol carbamate, SC), which can be subsequently hydrolyzed to 2-amino-1,3-propanediol (serinol), by reacting glycerol and urea: (I) In general, glycerol is heated with urea and a catalyst, with or without a solvent, to give mainly 4-hydroxymethyl-2-oxazolidinone (serinol carbamate, SC), which is hydrolyzed in the next step to 2-amino-1,3-propanediol (serinol). Alternatively, glycerol 1,2-carbonate can be used instead of glycerol. Serinol obtained by the process of the invention may be used in the synthesis of Iopamidol.
