Аннотация:(+/-)-alpha-Cyclogeraniol and (+/-)-drim-7-en-11-ol acetates obtained via the FSO3H-induced cyclisation of geraniol and (E)-farnesol and subsequent acetylation were hydrolysed in the presence of hog pancreas lipase (PPL) to afford (R)-(+)-alpha-cyclogeraniol (ee similar to30% at the optimal conversion C = 20+/-2%) and (5R,9R,10R)-(+)-drim-7-en-11-ol (ee 78.5% at C = 30%), respectively; (+/-)-15-acetoxy-isoagath-12-ene, obtained similarly from all-E-geranylgeraniol, is resistant to PPL-mediated hydrolysis, but is hydrolysed in the presence of lipase from Candida cylindracea to afford (10S,14R)-(-)-isoagath-12-en-15-ol of 69-80% ee in similar to3% yield.
