A recyclable Amberlyst-15-catalyzed three-component reaction in water to synthesize diarylmethyl sulfones

A recyclable Amberlyst-15-catalyzed three-component reaction in water was developed to synthesize asymmetric diarylmethyl sulfones in good to excellent yields with a wide substrate scope. Asymmetric diarylmethyl sulfones were prepared via C-C and C-S bond

Chemoselective Nucleophilic Functionalizations of Aromatic Aldehydes and Acetals via Pyridinium Salt Intermediates

The development of a novel chemoselective functionalization can diversify the strategy for synthesizing the target molecules. The perfect chemoselectivity between aromatic and aliphatic aldehydes is difficult to achieve by the previous methods. The aromatic aldehyde-selective nucleophilic addition in the presence of aliphatic aldehydes was newly accomplished. Namely, the aromatic aldehyde-selective nucleophilic addition using arenes and allyl silanes proceeded in the presence of trialkylsilyl triflate and 2,2′-bipyridyl, while the aliphatic aldehydes completely remained unchanged. The reactive pyridinium-type salt intermediate derived from an aromatic aldehyde chemoselectively underwent the nucleophilic substitution. Moreover, the aromatic acetals as the protected aldehydes could be directly transformed into similar pyridinium salt intermediates, which reacted with various nucleophiles coexisting with the aliphatic aldehydes.

Green synthesis and antiviral activity of novel triarylmethane derivatives via Friedel-Crafts alkylation by polyethylene glycol (PEG-400)

A series of novel triarylmethane derivatives (3a-j) were synthesized by a one-pot, two-component method via Friedel-Crafts alkylation of various electron-rich arenes (1a-j) with a wide variety of aldehydes (2a-j) in presence of the polyethylene glycol (PEG-400) as a green solvent at 50-60 °C in good to excellent yields (76-96 %). Their structures were confirmed by FT-IR, 1H NMR, 13C NMR, mass spectrometry and elemental analysis. All the triarylmethanes were tested and evaluated for their antiviral and antifungal activities. Compounds 3b, 3f, 3g and 3i exhibited highest antiviral activities against tobacco mosaic virus (TMV).
