A novel mono and/or double allylation of acetals is achieved by the action of ally1 bromide, aluminium metal, and a catalytic amount of PbBr2 and A1Br3 in tetrahydrofuran.

An electroreductive "Barbier Type" allylation of imines with ally1 bromide has been performed in a PbBqJ3uqNBqTI-G(Al anode)-(Pt cathode) system. A combination of Pb(O)/Pb(II) redox and a sacrificial aluminum anode works as a mediator for both cathodic and anodic electron transfer processes, respect
Barbier Type" allylation of imines with ally1 bromide has been performed successfully by the action of aluminum (1 equiv.) and titanium(W) chloride (0.05 equiv.) in THF. The chirality transfer of a-amino acid esters to homoallyl amines is demonstrated by allylation of N-benzalvaline methyl ester fol
