✦ Synopsis

We have reported that the reaction of 8-oxoheptafulvene with tropone and its derivatives afforded several products including (2 + 8)cycloadducts with cycloheptatriene and norcaradiene moieties, heptafulvalenes, and 1-oxaazulan-2-ones with cyclohexa-1,4-diene moiety at 3 and 4-positions, and we have also discussed the mechanisms of the formation of these products. 192) Further reactions of 8-oxoheptafulvene with several tropone derivatives were studied and we have found that other new reactions concerning the adducts, the results will be reported in this communication.
