| Description | In acidic medium the criss-cross cycloadduct with four fused five-membered rings rearranges to a heterocyclic compound with a completely different structure consisting of two six-membered and two five-membered rings. This newly discovered rearrangement was observed in the presence of a reducing agent (NaBH3CN). The rearrangement proceeds easily and with an extremely high yield. |
