A new type of direct vinylogousaldoladdition between cyclic β-haloenals and aromatic aldehydes promoted by TBAF has been developed. The reaction was carried out under mild conditions to provide highly functionalized δ-hydroxy-β-halo-α,β-unsaturated aldehydes with high diastereomeric ratios and low to good yields. direct vinylogousaldolreaction - TBAF - cyclic β-haloenals - regio- and diastereoselectivity
