Abstract
Dimethoxyethane is an useful solvent for the Schmidt reaction of ketones and β-ketoesters with sodium azide and methanesulfonic acid to afford amides and amidoesters. This solvent is an alternative to the unsafe chlorinated solvents normally used. A β-diketone and several (4S)-N-(2-alkylacctoacetyl)-4-benzyloxazolidin-2-ones afford oxazoles under those conditions.
