Abstract

2-Ketoindoline and 1-methyl-2-ketoindoline condense with hydroxymethylene ketones in the presence of hydrogen chloride to give pyrylium[2,3-b]indole chlorides, which can be converted to 5-(3-oxindolyl)-Δ2-pyrazolines by reaction with phenylhydrazine and to 5-(3-oxindolyl)-Δ2-isoxazolines by reaction with hydroxylamine.
