Substituted pyrrole derivatives are prepared by treatment of 2,3-dihydrofuran derivatives with trifluoroacetic acid. These in turn are obtained by Michael addition of carbon nucleophiles of the b-dicarbonyl type to N-(4-toluenesulfonyl)-N-(tertbutyloxycarbonyl)-dehydroalanine methyl ester.

O-2-(Acyl)vinylketoximes (freshly prepared from ketoximes and acylacetylenes in the presence of Ph 3 P as catalyst in up to 83% yields) rearrange upon heating (125-150 Β°C) to give 2-or 3-acylpyrroles, wherein the positions of the acyl substituents do not correspond to known O-vinyloxime rearrangemen
