Method for preparing alpha-hydroxymethionine analogs from sugars |
| abstract |
The present invention relates to a continuous flow process for the preparation of one or more alpha-hydroxymethionine analogs from sugars in the presence of a sulfur-containing compound, a solid Lewis acid catalyst, and a solvent comprising an organic solvent and water. The present invention provides a method for stabilizing a Lewis acid catalyst used in a continuous reaction process in which water is present in an amount greater than or equal to 10% by volume of the organic solvent. |
