4-Aryl-4-oxoesters undergo facile reduction of both the keto and the ester groups with methanolic NaBH4 at room temperature to yield the corresponding 1-aryl-1,4-butanediols whereas 4-alkyl-4-oxoesters furnish the corresponding 1,4-butanolides via selective reduction of the keto moiety. Results of a detailed and systematic investigation of the reaction are described.
4-芳基-4-氧代酯在室温下与甲醇中的NaBH4发生反应,可以轻易地同时还原其酮基和酯基,生成相应的1-芳基-1,4-丁二醇,而4-烷基-4-氧代酯则通过选择性地还原酮基部分,得到相应的1,4-丁内酯。本文详细描述了这一反应的全面和系统性的研究结果。
