1-Vinylpyrrole-2-carbaldehyde oximes: synthesis, isomerization, and spectral properties

The reaction of 1-vinylpyrrole-2-carbaldehydes with hydroxylamine hydrochloride in pyridine or ethanol in the presence of NaHCO 3 or NaOAc affords previously unknown 1-vinylpyrrole-2-carbaldehyde oximes in 95–99% yields. Isomerization of oximes from ( E ) to ( Z ) in the presence of strong acids and...

Zusammenfassung:	The reaction of 1-vinylpyrrole-2-carbaldehydes with hydroxylamine hydrochloride in pyridine or ethanol in the presence of NaHCO 3 or NaOAc affords previously unknown 1-vinylpyrrole-2-carbaldehyde oximes in 95–99% yields. Isomerization of oximes from ( E ) to ( Z ) in the presence of strong acids and the spectral characteristics of the isomers were studied. Graphical Abstract
