Novel 2,4,6-triazatetracyclo[5.3.2.0
2,6.0
8,10]dodec-11-ene-3,5-diones were prepared in high yields (86–96%)
via the hetero-Diels–Alder reaction of azodicarboxylic acid
N-phenylimide with 7-substituted cycloheptatrienes. The adducts are formed exclusively
via the
endo-addition of the azo dienophile to bicyclo[4.1.0]hepta-2,4-diene, the norcaradiene tautomer. The cyclopropane ring in the adduct is
syn-oriented relative to the double bond and contains an
exo-directed substituent.
