Process for the preparation of 2,4-didesoxihexosas and 2,4,6-tridesoxihexosas.

摘要

Process for preparing a 2, 4-deoxyhexose or 2, 4, 6-trideoxyhexose from a carbonyl compound unsubstituted or substituted with at least 2 carbon atoms and at least one hydrogen atom - and an aldehyde unsubstituted or substituted in the presence of an aldolase and water, wherein the reaction between the carbonyl compound unsubstituted or substituted with at least 2 carbon atoms and at least one hydrogen atom - and an aldehyde unsubstituted or substituted is carried out at a concentration carbonyl between 0, 6 and 6 moles / l of reaction mixture and the final concentration of 2, 4-dideoxyhexose or 2, 4, 6-trideoxyhexose is at least 2 mass% of the reaction mixture.
