Patent ID: 8273901

Claim:
A process of forming a pyrrole compound comprising: contacting an α-carbonyl oxime compound 1 wherein R 1 and R 2 are independently selected from the group consisting of H, a silyl-group, an aliphatic group, an alicyclic group, an aromatic group, an arylaliphatic group, an arylalicyclic group, the group —OR 10 and the group —NR 10 , wherein each moiety R 10 is independently selected from the group consisting of H, a silyl-group, an aliphatic group, an alicyclic group, an aromatic group, an arylaliphatic group, and an arylalicyclic group, the aliphatic, alicyclic, aromatic, arylaliphatic, and arylalicyclic groups comprised in R 1 , R 2 , and R 10 comprising 0 to about 3 heteroatoms selected from the group N, O, S, Se and Si, and an α,β-unsaturated aldehyde 2, wherein R 3 is selected from the group consisting of H, a silyl-group, an aliphatic group, and an alicyclic group, the aliphatic and alicyclic groups comprising 0 to about 3 heteroatoms selected from the group N, O, S, Se and Si, in the presence of a secondary amine in a suitable solvent for a sufficient period of time to allow the formation of an N-hydroxypyrrole compound 3,
