PROCESS FOR THE PREPARATION OF (R,S)-NICOTINE |
| 摘要 |
A process for (R,S)-nicotine is described. Condensation of 1-(but-1-enyl) pyrrolidin-2-one with nicotinic acid ester gave 1-(but-1-enyl)-3-nicotinoylpyrrolidin-2-one which on treatment with an acid and a base gave myosmine. Myosmine was converted to (R,S)-nicotine by reduction followed by N-methylation.
