The metalhydride mediated reduction of 4-carboethoxy-1,3-dimethyl-3-(methylthio)oxindole with lithiumaluminumhydride and lithium triethylborohydride was studied. The results show that reduction of the oxindole carbonyl group is competitive with reduction of the pendant ester. The hemi-aminal that results from initial addition of hydride to the oxindole carbonyl may follow a number of reaction pathways
