生物基线性二醇的合成是许多研究的主题。然而，工业发展的主要障碍之一是难以控制产品选择性。在这里，我们报告的催化转化糠醛为1，4-戊二醇（PD）的存在下，Ru负载在有序介孔碳（CMK-3）在H2和CO2的压力下在水中。与以前的催化途径相比，这项工作的不同之处在于它产生1，4-PD作为唯一的产物，而不是通常的1，2-和1，5-PD的混合物。在优化的反应条件下，以糠醛为原料，一锅法合成了1，4-PD，收率90%。我们公开了糠醛转化为1，4-PD遵循不寻常的催化途径。这意味着一个双功能的催化途径的基础上连续催化氢化反应和酸催化Piancatelli的重排。
The synthesis of bio-based linear diols is the subject of many research studies. However, one of the main obstacles in industrial development is the difficulty in controlling product selectivity. Here, we report the catalytic conversion of furfural to 1,4-pentanediol (PD) in the presence of Ru supported on an ordered mesoporous carbon (CMK-3) under pressure of H2 and CO2 in water. In contrast to previous catalytic pathways, this work is distinct in that it yields 1,4-PD as an exclusive product, instead of a mixture of 1,2- and 1,5-PD as usual. Under optimized conditions, 1,4-PD was obtained in 90% yield, and in a one-pot reaction, directly from furfural. We disclose that the conversion of furfural to 1,4-PD followed an unusual catalytic route. It implies a bifunctional catalytic pathway based on sequential catalytic hydrogenation reactions and an acid-catalyzed Piancatelli's rearrangement.
