Aminomethylation was accomplished by boiling the components of the mixture for 5 to i0 h in isoamyl alcohol. The reaction proceeded only at 4 < pH < 7. Arylfurans with electron donor groups or a substituent chlorine atom in the benzene ring were successfully introduced in the Mannich reaction. The attempt to aminomethylate Ie led to the formation of bis[2(p-nitrophenyl)furyl-5]methane (IIle). Analogous
Fine chemicals from HMF: A new short, efficient and malleable synthetic route for the production of bis(5-aryl-2-yl) methanescaffolds (present in coffee volatiles and licorice, and with multiple applications in polymer synthesis and cross-linking) is reported. This route avoids the use of protecting groups and utilizes readily available synthetic intermediates. A wide scope of the decarboxylative
