A NEW APPROACH FOR PREPARATION OF ATROPISOMERS OF ARYLPYRIDYLS VIA CROSS-COUPLING REACTIONS OF ARYL 2-(3-SUBSTITUTED)PYRIDYL SULFOXIDES WITH GRIGNARD AND ORGANOLITHIUM REAGENTS

Shibutani, Tadao,Fujihara, Hisashi,Furukawa, Naomichi

, p. 2943 - 2946 (2007/10/02)

The cross-coupling reactions of phenyl 2-(3-substituted)pyridyl sulfoxides with 2-methoxyphenyl- and 1-(2-methoxy)naphthyl Grignard and 2-phenoxyphenyl lithium reagents afforded atropisomers of arylpyridyl derivatives in good yields which undergo thermal epimerization.
