Enzymatic resolution of 2-acyl-3-hydroxymethyl-4-butanolide and preparation of optically active IM-2, the autoregulator from Streptomyces sp. FRI-5
摘要:
Racemic 2-acyl-3-hydroxymethyl-4-butanolides were resolved through a lipase-catalyzed acylation with acetic anhydride. Optically active forms of 2-butyryl-3-hydroxymethyl-4-butanolide 14 obtained were used to prepare enantiomers of IM-2 10, the autoregulator from Streptomyces sp. FRI-5. The absolute configuration of IM-2 was deduced to be (2R,3R,6R).
