Abstract

Lately, we have reported that organomanganese reagents react with cyclohexenone to give the 1,4 addition or the j3-reductive dimerixation product& ... R,M ti * THF a) Preparedjiom RMgX ... Unfortunately, the synthetic interest of these reactions is quite limited since, with most conjugated enones, they generally proceed in very poor yields (< 30 % ). Nevertheless, the study reported hereafter demonstrates that the ability of organomanganese reagents to add to a, ...
