Transformations of 2,2-dimethyl-2,4-dihydro-3H-pyrrol-3-on-1-oxide derivatives in the Vilsmeier-Haack reaction conditions

Enhydroxylaminones-2,2-dimethyl-2,4-dihydro-3H-pyrrol-3-on-1-oxides were shown to give various chlorinated products in the Vilsmeier-Haack reaction. The general sequence of the reaction steps is determined and the extent of the reaction was shown to be st

REACTION OF 2-SUBSTITUTED 5,5-DIMETHYL-4-OXO-1-PYRROLINE-1-OXIDES WITH ELECTROPHILIC REAGENTS

The reaction of β-oxonitrones, derivatives of pyrroline, with electrophilic reagents can proceed either at the oxygen atom of the nitrone group in the composition of the heterocyclic ring, or at the carbon atom between the carbonyl and nitrone group.
