We have achieved a divergent access to seven/five-membered rings based on a [1,6]-hydride shift/cyclization process from benzylidenemalonate with an o-alkoxymethyl group. Whereas Yb(OTf)3 afforded benzoxepines (with a seven-membered ring) selectively, indanes (with a five-membered ring) were the main products when Sc(OTf)3 was employed.

A series of variously functionalized selenium-containing compounds were purposely synthesized and evaluated against a panel of cancer cell lines. Most of the compounds showed an interesting cytotoxicity profile with compound 5 showing a potent activity on MCF7 cells. The ethyl amino derivative 5 acts synergistically with cis-platin and inhibits the GST enzyme with a potency that well correlates with the cytotoxicity observed in MCF7 cells. A computational analysis suggests a possible binding mode on the GST enzyme. As the main outcome of the present study, the ethyl amino derivative 5 emerged as a valid lead compound for further, future developments.

A method for the preparation of biaryl compounds is disclosed which comprises contacting an aryl halide under conditions suitable to form a Grignard reagent and thereafter contacting the Grignard reagent with an aryl chloride in the presence of a catalyst comprising a nickel compound and a coordinating ligand under conditions suitable for the formation of biaryl compound. In an alternate embodiment of the present invention, biaryl compounds are prepared directly from aryl halides in a single reaction vessel by contacting aryl halide with elemental magnesium and a nickel catalyst comprising a nickel compound and a coordinating ligand in an aprotic, non-polar, ether-containing solvent system for a time and under conditions suitable for the formation of biaryl compound.

A method for the preparation of biaryl compounds is disclosed which comprises contacting an aryl halide with a tertiary-alkyl organometallic reagent (or the precursor components thereof) in the presence of a catalyst comprising a nickel compound and a coordinating ligand under conditions suitable for the formation of biaryl compound. In an alternative embodiment of the present invention, nickel(0) compounds are prepared from nickel(II) compounds by contacting a nickel(II) compound with a combination of an organophosphine and a bidentate nitrogen-containing coordinating ligand, and a tertiary-alkyl organometallic reagent (or the precursor components thereof) in an aprotic, non-polar, ether-containing solvent system for a time and under conditions suitable for the formation of nickel(0) compound.

A method for the preparation of biaryl compounds is disclosed which comprises contacting an aromatic halide in the presence of a catalyst comprising zerovalent nickel, a bidentate phosphorus-containing coordinating ligand and a reducing metal in a polar, aprotic solvent system for a time and under conditions suitable for the formation of biaryl compound.
