Selective reduction of 1,4-diarylimidazoline-3-oxides to imidazolidin-1-ols and hydroxylamine derivatives
(Springer Wien, 2010)
C-2-unsubstituted imidazoline-3-oxides were reduced with NaBH4 in THF to give the corresponding trans-3,5-diarylimidazolidin-1-ols, while under the same conditions C-2-substituted derivatives gave the corresponding ...
Imidazolidin-1-oles, N-2-aminoethyl nitrones and 1,2,5-oxadiazinanes. A novel ring-chain tautomerism
(Pergamon-Elsevier Science Ltd, 2007)
Imidazolin-3-oxides I were reduced with NaBH4 in THF at reflux to give the corresponding 2,3,5-triarylimidazolidin-l-oles 2, which are proved to be in a ring-chain-ring tautomeric equilibrium with N-2-aminoethyl nitrones ...
