The titanium tetrachloride-catalyzed hydrodefluorination reaction of trifluorotoluene derivatives was developed using triethylsilane as the reducing agent. The reaction produced various toluene derivatives with high chemoselectivities by means of readily accessible reagents. This hydrodefluorination process was extended to the intramolecular Friedel-Crafts benzylation reaction, furnishing polycyclic aromatics of various ring sizes in good yields.

A direct result: Alkyl indium reagents are synthesized by the insertion of indium into alkyl halide mediated by CuCl. The synthetic utility of these reagents is demonstrated by their palladium-catalyzed coupling with aryl halides (see scheme). The reagents are compatible with various functional groups, and this makes the protocol generally useful in organic synthesis. DMA=N,N-dimethylacetamide, TBS=tert-butyldimethylsilyl.

With the aim to split the pharmacological properties of lefetamine (CAS 14148-99-3), some structural modifications of this compound have been studied. The basic group of lefetamine has been shifted from the alkyl chain to the vicinal phenyl ring and the N-substitution has been changed. The dimethylaminomethyl derivatives and chiefly the o-morpholinometyhl exhibited a strong anti-visceral chemical antinociception activity stripped of thermal antinociception properties and physical dependence liability. Furthermore through the introduction of a diethylaminomethyl group in the lefetamine structure some derivatives were selected exhibiting besided a significant increase in the anti-visceral chemical antinociception activity, remarkable local anesthetic properties.
