Condesations of 2-lithio-1-phenylsulphonylindole with the four pyridine analogues of phthalide gave 1-phenylsulphonylindol-2-yl o-hydroxymethylpyridyl ketones, from wich on treatment with base were obtained the title compounds, by a process of intramolecular indole β-nucleophilic substitution.This new aspect of indole chemistry is discussed in the context of other related processes.
