1,3-Dipolar cycloaddition of nitrones with alkenes in ionic liquids was written by Kolarovic, A.;Fisera, L.;Toma, S.;Pronayova, N.;Koos, M.. And the article was included in Polish Journal of Chemistry in 2007.Quality Control of 3-Acryloyloxazolidin-2-one This article mentions the following:
The first intermol. 1,3-dipolar cycloaddition of nitrones with alkene in ionic liquids is described. The ionic liquids were found to be effective media for the cycloaddition of dibenzylsubstituted nitrone or chiral sugar derived nitrones, e.g., I, with 3-acrylo-yl-1,3-oxazolidin-2-one. Excellent chem. yields (61-100%) and moderate diastereoselectivities can be achieved in imidazolium ionic solvents at room temperature The cycloaddition in ionic liquid is completely regioselective for chiral sugar derived nitrones in the absence or presence of Lewis acid with only the sterically favored 5-substituted isoxazolidines, e.g., II, being formed and for dibenzylsubstituted nitrone 5-substituted isoxazolidines are also major products. In the experiment, the researchers used many compounds, for example, 3-Acryloyloxazolidin-2-one (cas: 2043-21-2Quality Control of 3-Acryloyloxazolidin-2-one).
3-Acryloyloxazolidin-2-one (cas: 2043-21-2) belongs to oxazolidine derivatives. A common way to produce multisubstituted oxazolidines is by means of cycloaddition reactions. Oxazolidines are cyclic condensation products of β-amino alcohols and aldehydes or ketone, and they undergo a facile and complete hydrolysis in aqueous solution. Alterations in carbonyl moiety control the rate of formation of a given β-amino alcohol. Oxazolidines are weaker bases (pKa 6–7) than parent β-amino alcohols and found to be more lipophilic than the parent compound at physiological pH.Quality Control of 3-Acryloyloxazolidin-2-one
