An efficient Rh2(II,II)-catalyzed reaction has been developed under mild conditions. This synthetic method proceeds through iodination/oxidation of readily available isoquinolinium iodide salts under aerobic conditions with good to excellent yields. 4-Iodoisoquinolin-1(2H)-ones are important building blocks for biologically and medicinally important compounds. The developed methodology was applied to the gram-scale synthesis of a key intermediate in the synthesis of the CRTH2 antagonist CRA-680.

A straightforward Pd(II)-catalyzed general strategy was developed for the C5-selective arylation of the 2-pyridone core with easily available aryl iodides. The transformation was highly regioselective and accomplished with a wide scope and functional group tolerance. Silver nitrate played a crucial role in this direct site-selective arylation. The method was extended to synthesize biologically active molecules.

The catalyst-controlled C4/C8 site-selective C-H arylation of isoquinolones using aryliodonium salts as the coupling partners was developed. The C4-selective arylation was successfully achieved via an electrophilic palladation pathway. A completely differ

The new reduction reaction of the hydroxy groups of 4-hydroxy-4-phenyl- 1,2,3,4-tetrahydroisoquinolines (1) to the corresponding alkanes (2) with mineral and Lewis acids is reported. A stereoselective intermolecular hydride shift mechanism of the reduction was proved by reaction of the deuterated derivatives (14 and 15) of 1a with 10N HCl-C2H5OH and BBr3 in CH3CN.
Stereoselective intermolecular hydride shift mechanism of the new reduction of benzylic alcohols with acid

A stereoselective intermolecular hydride shift mechanism of the new reduction reaction of the benzylic hydroxy group of 4-hydroxy-4-phenyl-1,2,3,4-tetrahydroisoquinoline (1) to the corresponding alkane (2) with acid was proved by reaction of the deuterated derivatives (5 and 6) of 1.
A new synthetic route to 2-alkyl-4-aryl-1(2H)-isoquinolones and 2-alkyl-4-aryl-1,2,3,4-tetrahydroisoquinolines

4-Aryl and heteroaryl-1(2H)-isoquinolones have been prepared by base promoted cyclization of phosphorylated o-aroyl and heteroaroyl benzamides. Subsequent reduction of the carbonyl and styryl functions of the annulated products has given rise to 4-aryl-1,2,3,4-tetrahydroisoquinolines.
