Me. Sitzmann et al., FACILE FORMATION OF N-ALKYL-OXAZOLIDIN-2-ONES FROM N-ALKYL-NITROXYETHYLAMINES AND CARBONATE ANION IN BIPHASIC MEDIA, Tetrahedron letters, 39(45), 1998, pp. 8211-8212
Nitration of N-alkyl ethanolamines (1) followed by treatment of their
corresponding N-alkyl-N-(2-nitroxyethyl)amine salts (2) in a biphasic
CH2Cl2/aqueous Na2CO3 or NaHCO3 mixture at 25 degrees C gives N-alkyl-
oxazolidin-2-ones (3). This represents a new method that allows the pr
eparation of oxazolidinones at ambient temperature with the use of aqu
eous carbonate. Published by Elsevier Science Ltd.
