摘要：

Periselectvity in cycloaddition reactions of pentafulvenes with 3-oxidopyrylium betaines is examined. The results of our studies show that depending on the substituent on the C-6 carbon, the reaction may proceed either through the [6+3] or the [3+2] pathway. The results of our investigations with various pentafulvenes are discussed.
