A variety of functionalized triarylmethane and 1,1-diarylalkane derivatives were prepared via a transition-metal-free, one-pot and two-step procedure, involving the reaction of various benzal diacetates with organozinc reagents. A sequential cross-coupling is enabled by changing the solvent from THF to toluene, and a two-step SN1-type mechanism was proposed and evidenced by experimental studies. The synthetic utility of the method is further demonstrated by the synthesis of several biologically relevant molecules, such as an anti-tuberculosis agent, an anti-breast cancer agent, a precursor of a sphingosine-1-phosphate (S1P) receptor modulator, and a FLAP inhibitor.

Aryl and heteroaryl derivatives with an alkylaminoethyl chain on the hydroxyl group of the benzene ring are prepared and evaluated against Mycobacterium tuberculosis H37RV and showed the activity in the range of 3.12-25 μg/mL. The compounds containing alkylaminoethyl chains on aryl-chromeneyl carbinol do not show good activity. Similarly compounds with bis and tris-alkylaminoethyl chains on aryl and triarylmethane derivatives do not exhibit antitubcrcular activity. Among heteroaryl containing triarylmcthanes (TRAMs), thiophene derivatives with alkylaminoethyl chain on aromatic hydroxyl group have exhibited good antitubercular activity. On the other hand, pyrrole containing TRAMs do not show good activity.

A new series of thiophene containing triarylmethane derivatives were synthesized from the Friedel-Crafts alkylation of diarylcarbinols followed by incorporation of amino alkyl chains. These were evaluated against Mycobacterium tuberculosis H37Rv and showed the activity in the range of 3.12-12.5 μg/mL in vitro.
