名称:
Enzyme catalysed lactonization of 3,5 dihydroxy esters: Enantioselective synthesis of naturally occurring 3-hydroxy-5-decanolide, (−)-massoialactone, and 3-hydroxy-5-icosanolide.
摘要:
Synthesis of optically active (+)-3-hydroxy-5-decanolide, (-)-massoialactone and of the recently isolated 3-hydroxy-5-icosanolide was achieved by enzyme-catalysed lactonization of racemic 3,5 dihydroxy esters with PPL in dry Et2O . Ees vary from 86% up to > 98%.
