The reaction of β-amino alcohols with 1,1′-carbonyldiimidazole in dichloromethane is affected by the size of the nitrogen substituent. 1,3-Oxazolidin-2-ones are exclusively obtained from N-H, N-methyl and N-arylmethyl derivatives. O-(1-Imidazolyl)carbonyl derivatives are formed as intermediates from N-[1-(2-pyridyl)alkyl]-(S)-valinol and are mainly or exclusively converted into aziridines in the presence
β-氨基醇与 1,1'-羰基二咪唑在二氯甲烷中的反应受氮取代基大小的影响。1,3-Oxazolidin-2-ones 仅从 NH、N-甲基和 N-芳甲基衍生物中获得。O-(1-咪唑基)羰基衍生物作为中间体由 N-[1-(2-吡啶基)烷基]-(S)-缬氨醇形成,主要或仅在水存在下转化为氮丙啶,尽管环化是被三苯甲基等大的 N 取代基阻碍。
