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.
本文描述了一种制备(R,S)-尼古丁的过程。将1-(丁-1-烯基)吡咯烷-2-酮与烟酸酯缩合,得到1-(丁-1-烯基)-3-烟酰基吡咯烷-2-酮,经过酸和碱的处理后,生成肌烟碱。将肌烟碱还原后进行N-甲基化,即可制得(R,S)-尼古丁。
