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 , H2 , and Ru/C catalyst.

在Ru基催化剂的存在下，糠醛直接催化转化为呋喃衍生的胺。

由生物质生产胺中间体正引起越来越多的关注。本文中，开发了一种简单有效的制备呋喃衍生的胺的方法[例如1-（呋喃-2-基）-4-甲基戊烷-2-胺]，其从（E）- 1-（呋喃-2-基）-5-甲基己基-1-en-3-一个。所使用的催化剂为Ru / C，并且可循环使用至第四周期。为了进一步实现成本效益，尝试了一种单反应器串联概念。为了这个目的，研究了糠醛的直接反应。在甲基异丁基酮，NH3，H2和Ru / C催化剂的存在下，从糠醛直接开始，可实现对1-（呋喃-2-基）-4-甲基戊基-2-胺的高收率（74％）。
