Abstract

The invention discloses a carbon dioxide one-pot method for directly preparing oxazolidine-2-one compounds. The method comprises the following steps: adding a catalytic amount of ionic liquid into epoxy compounds, carrying out reactions under a primary pressure of CO2, then adding aniline or aniline derivatives, and making the reactions going on so as to prepare the oxazolidine-2-one compounds. The carbon dioxide one-pot method has the advantages of no need to separate intermediate products, little using amount of catalyst, safe reaction operation, mild reaction conditions, no addition of any organic solvent in the reaction process, and environment-friendliness.

Description

technical field

[0001] The invention belongs to the technical field of organic synthesis methods, and in particular relates to a method for directly preparing oxazolidin-2-one compounds by a carbon dioxide one-pot method. Background technique

[0002] CO 2 is the main greenhouse gas on earth, reducing CO 2 Emissions are a major strategic issue for governments, science and industry today. However, with the growth of the world population and the improvement of modernization, the human demand for energy is increasing rapidly, which inevitably causes CO 2 increase in emissions; therefore, how to minimize CO 2 At the same time as the emission, the enriched CO 2 The transformation of resources into energy, materials and fine chemical products has attracted the attention of many scientists (Science in China: Chemistry 41 (2011) 925-932).

[0003] The "one-pot method" is a promising organic synthesis method. The multi-step reaction in the one-pot reaction can directly obtain m...
