Enzymatic resolution of 1,1-dimethoxybut-3-en-2-ol and 1,1-dimethoxypent-4-en-2-ol, α-hydroxyaldehyde precursors for aldol-type reactions
摘要:
Hydroxyacetals 2 and 3 were resolved by acylation with vinyl acetate in the presence of lipases in organic media. The reverse reaction, the enzymatic hydrolysis of the corresponding acetates, was also highly stereoselective and provided the opposite enantiomers. (c) 2005 Elsevier Ltd. All rights reserved.
