Process for the preparation of L-aspartic acid N-thiocarboxyanhydride |
| abstract |
An improved process for the preparation of L-aspartic acid N-thiocarboxyanhydride by the reaction of a 0.75 to 1.25 molar solution of an N-alkoxy-thiocarbonyl L-aspartic acid in a lower alkyl acetate solvent with a phosphorous trihalide. The desired product is substantially insoluble in the lower alkyl acetate solvent and is recovered in pure form without further purification or separation steps. |
