Tetrabutylammonium salts serve as templates for the Norrish-Yang cyclization of 2-benzyloxy-acylbenzenes to give trans-dihydrobenzofuranols in high stereoselectivities. The dual cation-π interactions between an ammonium with a benzene ring and a carbonyl group play a key role in changing the conformation of the substrate, which was supported by ab initio calculations.

A series of 2-amino-3-cyano-4-alkyl-6-(2-hydroxyphenyl)pyridine derivatives was synthesized and evaluated as IκB kinase β (IKK-β) inhibitors. Modification of a novel IKK-β inhibitor 1 (IKK-β IC 50=1500nM, Cell IC50=8000nM) at the 4-p
Conjugate addition to 3-arylsulfinylchromones as a synthetic route to homochiral 2-substituted chromanones: Scope and limitations

A route to homochiral 2-substituted chromanones via the diastereoselective conjugate addition of organocopper reagents to 3-(p-tolylsulfinyl)chromones has been improved and used to prepare 2,6-dimethylchromanone (S)-4 and LL-D253α methyl ether (S)-6. The attempted preparation of a 2-phenylchromanone (flavanone) using this strategy was unsuccessful due to the lability of the intermediate 2-phenyl-3-(p-tolylsulfinyl)chromanone, which underwent sulfoxide elimination at room temperature to give the corresponding 2-phenylchromone (flavone).
