A new organocatalytic system was tested as a promoter for the asymmetric addition of Chan's diene to aldehydes under solventfree conditions. This new organocatalyst generated in situ by mixing 1-naphthyl-TADDOL derivative and Emim BF 4 was able to give enantioenriched vinylogous aldols and hetero-Di
