✦ Synopsis

We have reported cycloadditions of 3-oxidopyridinium betaines 1 in which they act as 4v-components (adding 2v2 or 6v3 addends across the 2,6-positions) or as 2uf 6wcomponents (adding thermally 4w4 or photo~emi#Hy 2w/6u5 addends across the 2,4-

heptafulvene, 8, undergoes both an intramolecular [8+21 cycloaddition and a loll-electron electrocyclization followed by 1,5-sigmatropic hydrogen shifts to give 10 and 12, respectively. Acetylheptafulvene, 1, was reported to be unstable by Hafner,' although the reaction of 1 with DMAD to give an in
