3-(4-Phosphoryl-4-methyl-2-oxopentyl)-3-hydroxyindolin-2-ones, the first phosphorus analogues of natural convolutamydines

Abstract

© 2018 The first examples of phosphorus-containing analogues of natural alkaloids, convolutamydines, have been obtained by aldol condensation of 4-[dialkyl(diphenyl)phosphoryl]-4-methylpentan-2-one with isatin. An unusually facile reversible process of dehydration–hydration of these phosphorus-containing hydroxy indoles has been discovered.
