Abstract: Reaction of cyclohexan-1,4-dione with different active methylene heterocycles affords tetrahydroquinodimethane derivatives, in moderate to good yield. Semiempirical calculations indicate that introduction of double bonds in tetrahydroquinodimethane stabilizes the system due to the extended conjugation. All the synthesized products have been characterized by spectral techniques and their conformations ascertained by MO calculations.
