Popis:	By the reaction of 3-aryl-1H-benzo[f]chromenes with N-bromosuccinimide in aqueous acetone, a series of 2-aroyl-1,2-dihydronaphtho-[2,1-b]furans unsubstituted at the C-1 position were obtained as a result of formal addition of hypobromous acid to the pyran fragment and intramolecular nucleophilic substitution. This reaction is a rare example of the ring constriction in 1H-benzo[f]chromene series.
