✦ Synopsis
Abstract
Several acetyl derivatives of linearol, atractyligenin and atractylitriol were obtained through enzyme‐catalysed acetylation and deacetylation reactions. In most reactions lipases showed regio‐ and stereoselective behaviour, allowing a family of novel compounds to be prepared. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)

## Abstract __ent__‐Kaurane diterpenoids are a class of natural compounds isolated from genus __Isodon__, which have been found to have important bioactivities. Negative electrospray ionization tandem mass spectrometry ((−)ESI‐MS^__n__^) was used to investigate the fragmentation pattern of C‐20‐non
