The expansion of heterocyclic rings

1955
Of the reactions in which pyrroles and indoles are reported to undergo ring expansion, the example investigated initially - the conversion of 2-carbamyl-2-cyano-dihydroindole to 3-carbamyl-2-hydroxyquinoline - proved to be incorrect. The supposed dihydroindole compound (a reduction product of alpha-cyano-o-nitrocinnamamide) was actually 2-amino-3 ...
