Highly Regioselective Monoalkylation of Ketones via Manganese Enolates. Prepared from Lithium Enolates

Cahiez, Gerard,Chau, Khi,Clery, Patrick

, p. 3069 - 3072 (1994)

Li-enolates are readily converted to Mn-enolates by treatment with manganese halides.In THF, the reaction is easily and economically performed with manganese chloride at room temperature.Mn-enolates can then be regioselectively monoalkylated in good yields.The formation of di and polyalkylated products is never observed (1percent).
