A direct and enantioselective oxidative cross-coupling of racemic 2,2-diarylacetonitriles with electron-rich (hetero)arenes has been described, which allows for efficient construction of triarylmethanes bearing all-carbon quaternary stereocenters with excellent chemo- and enantioselectivity. The reaction has an excellent functional group tolerance, and exhibits a broad scope with respect to both 2

Aminoalkyl derivatives of diarylmethanes were prepared using Grignard, Friedel-Craftsarylation and aminohydrochloride chain formation reactions. These series of compounds were evaluated against Mycobacterium tuberculosis H(37)R(v) and showed the activity in the range of 6.25-25 microg/mL.
