Enantiomeric separation of racemic nicotine by addition of an O,O'-disubstituted tartaric acid enantiomer |
| abstract |
The present invention relates to a method of separating racemic nicotine of Formula (l-a) as a mixture of the (R)- and (S)-enantiomers into the enantiomerically pure (S)- and (R)-nicotine represented by Formula (l-b) and (l-c), by adding a mixture of the L- and the D-enantiomer of a O,O'-disubstituted tartaric acid, wherein the molar ratio of the L- to the D-enantiomer is from 80:20 to 95:5, and obtaining the (S)-nicotine of formula (l-b), or by adding O,O'-dibenzoyl-D-tartaric acid and obtaining the (R)-nicotine of formula (l-c). |
