A novel and practical synthesis of dinotefuran 1, featuring a new access to it from known key intermediate (tetrahydrofuran-3-yl)-methanamine 5, has been achieved through Michael addition reaction of nitromethane to diethyl maleate in 6 steps with 45.5% total yield. This synthesis is scalable and hence has high potential for application to further synthetic elaboration on such new neonicotinoid insecticide dinotefuran 1.

The development of heterogeneous, chemoselective, and tandem catalytic systems using abundant metals is vital for the sustainable synthesis of fine and commodity chemicals. We report a robust and recyclable single-site cobalt-hydride catalyst based on a porous aluminum metal–organic framework (DUT-5 MOF) for chemoselective hydrogenation of arenes. The DUT-5 node-supported cobalt(II) hydride (DUT-5-CoH) is a versatile solid catalyst for chemoselective hydrogenation of a range of nonpolar and polar arenes, including heteroarenes such as pyridines, quinolines, isoquinolines, indoles, and furans to afford cycloalkanes and saturated heterocycles in excellent yields. DUT-5-CoH exhibited excellent functional group tolerance and could be reusable at least five times without decreased activity. The same MOF-Co catalyst was also efficient for tandem hydrogenation–hydrodeoxygenation of aryl carbonyl compounds, including biomass-derived platform molecules such as furfural and hydroxymethylfurfural to cycloalkanes. In the case of hydrogenation of cumene, our spectroscopic, kinetic, and density functional theory (DFT) studies suggest the insertion of a trisubstituted alkene intermediate into the Co–H bond occurring in the turnover limiting step. Our work highlights the potential of MOF-supported single-site base–metal catalysts for sustainable and environment-friendly industrial production of chemicals and biofuels.

The invention provides a synthetic method for 3-aminomethyl tetrahydrofuran. A target product, namely the 3-aminomethyl tetrahydrofuran is prepared by taking 2,5-dihydrofuran as an initial raw material. In the whole synthesis process, the synthesis method has the advantages of green and environmentally-friendly used raw materials, mild and conveniently-controllable reaction conditions, safe production, low risk, simple process, high yield, and more applicability to industrial production.
