从生物质中生产胺中间体正受到越来越多的关注。本研究以(E)-1-（呋喃-2-基）-5-甲基己烯-1-烯-3-酮为原料，制备了1-（呋喃-2-基）-4-甲基戊烷-2-胺，收率高达95%。催化剂为Ru/C，可循环使用至第四次循环。为了进一步实现成本效益，尝试了单反应器串联概念。为此，研究了糠醛的直接反应。在甲基异丁基酮、NH3、H-2和Ru/C催化剂的存在下，从糠醛直接合成1-（呋喃-2-基）-4-甲基戊胺的收率可达74%。
The production of amine intermediates from biomass is capturing increasing attention. Herein, a simple and efficient preparation of l furan-derived amines was developed [e.g., 1-(furan-2-yl)-4-methylpentan-2-amine] with high yield (up to 95 %) from (E)-1-(furan-2-yl)-5-methylhex-1-en-3-one. The catalyst used was Ru/C, and it was recyclable up to the fourth cycle. To further realize cost-efficiency, a one-reactor tandem concept was attempted. To this aim direct reaction from furfural was investigated. A high yield (74 %) towards 1-(furan-2-yl)-4-methylpentan-2-amine could be achieved starting directly from furfural in the presence of methyl isobutyl ketone, NH3, H-2, and Ru/C catalyst.
