The synthesis of new 3-[(acyl(or alkyl)thio)methyl]-1-hydroxy-2-phenylindoles 1 are presented. The substrates 2 obtained by each efficient three-step synthesis were treated, in the presence of SnCl2 center dot 2H(2)O, with nucleophiles such as thiocarboxylic acids and thiols to provide target compounds 1 by successive processes of nitro reduction and intramolecular condensation, followed by addition of nucleophile. Analyses of the reaction mechanism, including the effects of substituents along with the reactivity of nucleophiles, are described.
