Preparation of catechol derivatives

, (2008/06/13)
A method of preparing derivatives of aromatic compounds including the catechol function STR1 by replacement of one of the hydroxyls by mercaptan STR2 Cathechol or a multi-ring compound (naphthyl-, anthryl-, phenanthryl-, etc.) containing the catechol function is first reacted with thiophosgene to produce the corresponding dioxole-2-thione STR3 The thione is ammonolyzed to the corresponding hydroxy N,N-disubstituted thionocarbamate STR4 The thionocarbamate is acetylated to STR5 and heated to rearrange the compound to the corresponding thiolcarbamate STR6 Further heating produces the corresponding oxathiol-2-one STR7 which can be hydrolyzed to the corresponding mercaptan STR8
