[EN] INDUSTRIAL SYNTHESIS OF SERINOL [FR] SYNTHÈSE INDUSTRIELLE DE SÉRINOL
摘要:
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.

receptor (EGFR), via competitive binding at the ATP site of the enzyme, but many of the early analogues had poor aqueous solubility (<< 1 mM). A series of 7-substituted 4-[(3-bromophenyl)-amino]pyrido[4,3-d]pyrimidines, together with selected (3-methylphenyl)amino analogues, were prepared by reaction of the analogous 7-fluoro derivatives with appropriate amine nucleophiles in 2-BuOH or aqueous 1-PrOH.

A comparative study of the copper metallocenter coordination sphere is carried out for a series of N-substituted β-alaninate ligands in condensed phase. For the elucidation of the effect of regular changes in dentate properties of a ligand on the complex structure, N-(bis(hydroxymethyl)methyl)-β-alanine and its copper(II) complex are specially synthesized and the complex structure is studied by the
