α-酮酯和α-酮酰胺的Henry反应

Henry Reaction of α-Ketoesters and α-Ketoamides

用三乙胺催化环状α-酮酯和α-酮酰胺同硝基甲烷的Henry反应,首次合成了12个多官能团的β-硝基醇,它们的结构用元素分析、红外光谱和核磁共振进行了表征.这一反应速度较快,室温下进行,条件温和,产率较好,是合成多官能团硝基醇的有效方法.

The Henry reaction of cyclic α-ketoesters and α-ketoamides was achieved using triethylamine as a promoter. Twelve new multi-functional β-nitroalcohols were synthesized. Their structures were confirmed by elemental analyses, IR, ^1H NMR or ^13C NMR spectroscopy, β-Nitroalcohols were produced in high yields under mild reaction conditions.
