Unsymmetrical E- and Z-stilbenes can be synthesized from two differently substituted benzaldehydes in a MesP(TMS)Li-promoted reductive coupling sequence. Depending on the order of addition of the two coupling partners, the same olefin can be produced in either E- or Z-enriched form under identical reaction conditions. A systematic study of the correlation between the stereochemical outcome of the reaction and the substitution pattern at the two aldehydes is presented. The results can be used as guidelines to predict the product stereochemistry. This journal is

A phosphoric acid catalyzed atroposelective Friedl?nder reaction was developed in which acetylacetone and a variety of 2′-substituted 2-Aminobenzophenones were successfully employed to give optically active biaryl quinolines in good yields and with high enantioselectivities.
Hf(OTf)4-Catalyzed highly diastereoselective synthesis of 1,3-disubstituted tetralin derivatives via benzylic C(sp3)-H bond functionalization

We report a highly diastereoselective synthesis of 1,3-disubstituted tetralin derivatives via Lewis acid catalyzed benzylic C(sp3)-H bond functionalization. The employment of Hf(OTf)4 as an acid catalyst was crucial in the reaction,
Stereocontrolled synthesis of carbon-carbon double bond locked analogues of strobilurins which are characterized by a trans-1,2-disubstituted cyclopropane ring

The racemic forms of four new carbon-carbon double bond locked analogues of strobilurins, which are characterized by a trans-1,2-disubstituted cyclopropane ring, have been synthesized according to a strategy which involves palladium-catalyzed cross-coupli
A New Phenanthrene Synthesis
Brown, Charles,Sikkel, Bernardus J.,Carvalho, Christopher F.,Sargent, Melvyn V.
, p. 3007 - 3010 (2007/10/02)
Substituted (Z)-2-chlorostilbenes give good yields of phenanthrenes on treatment with activated magnesium formed by the reduction of magnesium chloride with potassium in the presence of potassium iodide in boiling tetrahydrofuran.A homolytic substitution mechanism is proposed for this reaction.
