N-Substituted 5-Aryl-1,3-oxazolidin-2-ones from Arylethylene Oxides

摘要

Substituted 5-aryl-1,3-oxazolidin-2-ones can be efficiently prepared from arylethylene oxides and tert-butyl alkylcarbamates in the presence of catalytic amount of potassium tert-butoxide as a base.Their further hydrolysis under basic conditions provides aryl substituted aminoethanols in high yields.
