The first total synthesis of melovinone, a nonrutaceous 3-methoxy-4-quinolone alkaloid isolated from Melochia tomentosa L., is reported. The target was acquired in a convergent fashion through the Suzuki-Miyaura cross-coupling reaction between an ortho-nitrobenzoic acid acetonyl ester derivative prepared from vanillin and potassium 5-phenyl-1-pentyltrifluoroborate, obtained from β-phenethyl bromide. The coupling was followed by a chemoselective reduction of the nitro group and a microwave-Assisted and AcOH-promoted cyclization with rearrangement of the resulting acetonyl anthranilate. This afforded a pseudane intermediate, which was selectively methylated on the 3-OH. The synthetic pathway enabled to reach the objective in 11 steps and 18% overall yield. The 1 H NMR spectra of the synthetic and natural product were in full agreement.

Three (E)-5-bromo-2-methoxy-4-((phenylimino)methyl)phenol derivatives (1-3) are synthesized and characterized by elemental analysis and single-crystal X-ray diffraction. The antibacterial activities of compounds 1-3 against Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis, and Staphylococcus aureus are evaluated by the MTT method.
