The first efficient palladium-catalyzed asymmetric hydrogenation of 2-aryl cyclic ketones has been described through dynamic kinetic resolution under acidic conditions, providing a facile access to chiraltranscycloalkanol derivatives with excellent enantioselectivities.

An enantioselective catalytic inverse-electron-demand Diels-Alder reaction of salicylaldehyde acetal-derived oxocarbenium ions and vinyl ethers to generate 2,4-dioxychromanes is described. Chiral pentacarboxycyclopentadiene (PCCP) acids are found to be effective for a variety of substrates. Computational and X-ray crystallographic analyses support the unique hypothesis that an anion with point-chirality-induced helical chirality dictates the absolute sense of stereochemistry in this reaction.

Strong competition: A method for the meta-selective arylation of the highly versatile α-aryl carbonyl motif using diaryliodonium salts is described. In this CuII-catalyzed process the remote carbonyl group is capable of overpowering even strongly para-directing functionalities to form the elusive meta-products (see scheme). Remarkably, the arylation process can also operate under metal-free conditions.

(Matrix Presented) New Lewis acid-assisted Bronsted acids (LBAs), tin(IV) chloride-2,6-dialkoxyphenols, serve as artificial cyclases for biomimetic polyene cyclization. For example, the enantioselective cyclization of 4-(homogeranyl)toluene using tin(IV) chloride-2,6-di[(1′R,2′R)- trans-2′-(3″,5″-xylyl)cyclohexanoxy]-phenol gave a trans-fused tricyclic compound with 85% ee.
Enzymatic resolution of trans-2-arylcyclohexan-1-ols using crude chicken liver esterase (CCLE) as biocatalyst

Homochiral trans-2-arylcyclohexan-1-ols were synthesized via crude chicken liver esterase (CCLE) mediated enantioselective hydrolysis of the corresponding racemic acetates.
