A new, practical synthesis of the antirheumatic oxindole derivative, tenidap, has been elaborated. The new approach has initiated studies on the mechanism of the acylation reactions of oxindoles. Methods have been developed for the synthesis of 1-[alkoxy(or aryloxy)carbonyl]- and 1,3-di[alkoxy(or aryloxy)carbonyl]oxindoles starting from oxindoles. The route designed for tenidap has provided a facile access to several analogues, too. On another front, new reaction conditions are described, which turn Wenkert's synthesis of 3-alkyloxindoles (by Raney nickel induced alkylation of oxindoles with alcohols) into a highly efficient synthetic tool. The method has been extended to the synthesis of 3-alkyloxindoles from isatins and to the preparation of 3-(ω-hydroxyalkyl)oxindoles from oxindoles and isatins. Springer-Verlag 2004.

Protection of amide nitrogen of oxindole and methyloxindole using Boc and Z-groups has been described. Sodium carbonate was found to be an effective base for these protections.
