Synthèse en une étape par voie organométallique de diamines primaires benzyliques α, α′-disubstituées
摘要:
We describe a convenient pathway to prepare primary benzylic diamines with allylic or propargylic groups in alpha- and alpha'-positions, by of the regiospecific reaction between organometallics (M = Zn, Al, Mg) prepared from allylic or propargylic bromides and the bis-N-trimethylsilylimines resulting from an aromatic 1,3- or 1,4-dialdehyde.
