| 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. |
