• Systematic investigations on the reduction of 4-aryl-4-oxoesters to 1-aryl-1,4-butanediols with methanolic sodium borohydride

  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。

  4-difluoro-4-(4′-aminophenyl) butanoate, since this amine was hydrolytically unstable. Reaction of methyl 4-(3′-nitrophenyl)-4-oxobutanoate with sulfur tetrafluoride, followed by hydrogénation, afforded the stable isomer, methyl 4,4-difluoro-4-(3′-aminophenyl)butanoate. Bis(hydroxyethylation) by treatment with oxirane, conversion of OH to Cl by Ph3P/ CCL4, and then hydrolysis of the ester group, gave 4-[3′-

  Dehydrogenation by IBX/p‐TsOH is applied to the conversion of 3‐benzoyl propionates/propionamides to 3‐benzoyl acrylates/acrylamides in moderate to excellent yields. The reaction time for the dehydrogenation of 3‐benzoyl propionamides was remarkably shorter than that for the dehydrogenation of esters.
