Resumo: | A new and efficient metal-free entry to hydroazulenones is reported. Enyneacetals were easily converted into hydroazulene skeletons by tandem Brønsted-acidpromoted carbocyclizations followed by stereospecific Nazarov cyclizations. The versatility of this transformation also allowed assembly of interesting heteroaromatic tricyclic systems. |
