RESUMEN

A novel TBAF-promoted intermolecular crossed-conjugate addition has been developed. For a range of cyclic ß-halo-α,ß-unsaturated carbonyl compounds, the vinylogous enolates generated by deprotonation at the Î³-position preferentially reacted with Michael acceptors at the α-position to deliver cross-coupling products in good yields.

Asymmetric organocatalytic four-component quadruple domino reaction initiated by oxa-Michael addition of alcohols to acrolein.
