Abstract
극성 용매인 물과 비극성 용매인 염화메틸렌에서 각각 니코틴을 당량의 오존과 반응시켜 그 생성물을 기체 크로마토그라피로 조사한 후 관 크로마토그래피 및 얇은 막 크로마토그래피를 이용하여 분리하였다. 이들 6가지 물질을 NMR, IR 및 Mass로 구조를 확인한 결과, 미반응의 니코틴 l-nornicotine, anabasine, β-nicotyrine, cotinine 및 nicotine-N-oxide임이 밝혀졌다. 이 생성물들을 토대로 두 액상에서의 니코틴 오존화 반응은 피롤리딘 고리의 1'위치에서 1차 산화가 일어나는 반응 메카니즘을 제안하였다.

Nicotine was reacted with an equimolar amount of ozone in methylene chloride and distilled water. The reaction mixture was separated by column chromatography or thin layer chromatography and then purified by vacuum distillation. The six compounds obtained from this reaction were characterized by NMR, IR and Mass spectrometry. These were identified as unchanged nicotine, nornicotine, anabasine, β-nicotyrine, cotinine and nicotine-N-oxide. From these results, reaction mechanism for the ozonolysis ofon nicotine was proposed; the pyrrolidine ring is attacked by ozone at the 1'-position followed by further transformation.
