This article provides an overview about specifically modified Mannich reactions where the process involves an ortho-quinone methide (o-QM) intermediate. The reactions are classified on the basis of the o-QM source followed by the reactant, e.g., the dienophile partner in cycloaddition reactions (C=C or C=N dienophiles) or by the formation of multicomponent Mannich adducts. Due to the important pharmacological activities of these reactive o-QM intermediates, special attention is paid to the biological activity of these compounds.

3‐methyl‐1‐sulfonic acid imidazolium tetrachloroferrate {[Msim]FeCl4} was prepared and fully characterized by fourier transform infrared spectroscopy (FT‐IR), X‐ray diffraction (XRD), thermal gravimetric analysis (TGA), differential thermal gravimetric (DTG), field emission scanning electron microscopy (FESEM), energy dispersive X‐ray analysis (EDX) and vibrating sample magnetometer (VSM) and used, as an efficient catalyst, for the tandem reaction of β‐naphthol with aromatic aldehydes and benzamide at 110 °C under solvent‐free conditions to give 1‐amidoalkyl‐2‐naphthols in high yields and very short reaction times.

Efficient One-Pot Syntheses of Betti Bases Catalyzed by 1-Methyl-3-(2-(sulfooxy)ethyl)-1H-imidazol-3-ium Chloride. -Two slightly different approaches to Betti bases are given. The application of the reusable pyridine-based ionic liquid emerges as crucial for satisfying yields. -(WANG, C.; WAN, Y.; WANG, H.-Y.; ZHAO, L.-L.; SHI, J.-J.; ZHANG, X.-X.; WU*, H.; J. Heterocycl.
