ermine — in which there are 6 adjacent chiral centres and 8 contiguous carbon atoms containing functional groups from eight carbon sugar lactones — depend on efficient cyclisations to give piperidines with trans-acetonides as protecting groups. Inhibition of naringinase (L-rhamnosidase) by 2S-2-hydroxy-6-epicastanospermine and 2S-2-hydroxycastanospermine may be due to a structural resemblance to the
2S-2-羟基castanospermine以及2R-和2S-2-羟基-6- Epi Castanospermine的短合成(其中有6个相邻的手性中心和8个连续的碳原子,这些碳原子包含来自8个碳糖内酯的官能团)取决于有效的环化得到具有反式丙酮化物作为保护基的哌啶。2S-2-羟基-6-表位粟精胺和2S-2-羟基castanospermine对柚皮苷酶(L-鼠李糖苷酶)的抑制作用可能是由于其与非天然L-(+)-swainsonine的结构相似。
