摘要

N-substituted 2-oxazolidones have been prepared from isocyanates and epoxides in refluxing DMF with lithium chloride as catalyst. Although the major products are &substituted 2-oxazolidones, 4substituted isomers were also isolated in several cases. The nmr spectra of the 2-oxazolidones were determined, and chemical shift-structure relationships are reported.
