Preparation of N-Formyl- and N-carbomethoxy-2,3-dihydropyrroles by palladium-catalyzed isomerization of the corresponding N-acyl-2,5-dihydropyrrole

Abstract

N-Formyl- and N-carbomethoxy-2,3-dihydropyrrole were prepared by palladium acetate / dppp catalyzed isomerization of N-formyl- and N-carbomethoxy-2,5-dihydropyrrole, respectively, in the presence of N,N-diisopropylethylamine and trifluoroacetic acid.
