Abstract Efficient enantioselective synthesis of (R)- and (S)-enantiomers of 2-(tert-butylamino)-1-(p-methoxyphenyl)-ethanol has been achieved in high enantiomeric excess by using asymmetric sulfoxide as a chiral auxiliary. The present synthetic approach was further extended to the asymmetric synthesis of (R)-salbutamol.
摘要 通过使用不对称亚砜作为手性助剂,以高对映体过量实现了 2-(叔丁基氨基)-1-(对甲氧基苯基)-乙醇的 (R)- 和 (S)- 对映体的高效对映选择性合成。目前的合成方法进一步扩展到 (R)-沙丁胺醇的不对称合成。
