An efficient and facile method for the regioselective synthesis of novel dihydrobenzo[a]fluorenes from readily accessible alkynols is presented. The current strategy triggers the formation of a dual C-C bond intramolecularly via Lewis acid catalysis under mild reaction conditions. Notably, secondary as well as tertiary alcohols bearing an alkyne moiety have been smoothly transformed into the corresponding products. As a result, novel tetracyclic dihydrobenzo[a]fluorenes have been accomplished using this approach.

A simple and practical method has been developed based on intermolecular [Pd]-catalyzed C-C and an intramolecular [Cu]-catalyzed C-O bond formations for the synthesis of flavans and benzoxepines. Interestingly, the method is amenable for the synthesis of
