The metal hydride mediated reduction of 4-carboethoxy-1,3-dimethyl-3-(methylthio)oxindole with lithium aluminum hydride 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
研究了金属氢化物介导的 4-carboethoxy-1,3-二甲基-3-(甲硫基)oxindole 与氢化铝锂和三乙基硼氢化锂的还原反应。结果表明羟吲哚羰基的还原与侧酯的还原竞争。由氢化物最初加成到羟吲哚羰基上产生的半缩醛可能遵循许多反应途径,其中之一是前所未有的重排。提出了一种机制来解释所有观察到的产品。关键词:羟吲哚,还原,重排。
