INTRAMOLEKULARE (4+2)-CYCLOADDITIONEN MIT INVERSEM ELEKTRONENBEDARF
Schuster, H.,Sauer, J.
, p. 4087 - 4090 (2007/10/02)
1,2,4,5-Tetrazines, 1,2,4-triazines, α-pyrones and cyclopentadienones are reacted with bifunctional dienophiles 6 - 9 to yield semibullvalenes, snoutenes, azasnoutenes and polycyclic azo compounds or carbocycles in few steps.
CYCLOADDITION VON N-PHENYLTRIAZOLINDION AN 1,5-DIALKYL SUBSTITUIERTE SEMIBULLVALENE
Askani, R.,Kirsten, R.,Dugall, B.
, p. 4437 - 4444 (2007/10/02)
Starting from bicycloocta-3,7-diones, several 3- and 7-substituted semibullvalenes were prepared.Cycloaddition of N-phenyltriazolindione to some of these semibullvalenes lead with rearrangement of the carbon skeleton to dihydrdioazatriquinacenes.De

Starting from bicyclo[3.3.0]octa-3,7-diones, several 3- and 7-substituted semibullvalenes were prepared. Cycloaddition of N-phenyltriazolindione to some of these semibullvalenes lead with rearrangement of the carbon skeleton to dihydrodiazatriquinacenes.
