Reduction of 2,6-diacetoxy-2′-bromoacetophenone (10) with NaBH4 led to 3,4-diacetoxydihydrobenzofuran (12) in a process involving acyl migration followed by cyclization. Subsequent hydrogenolysis gave 4-acetoxydihydrobenzofuran which, upon saponification, afforded 4-hydroxydihydrobenzofuran (8) in good yield. This approach is shown to be a general method for preparation of substituted dihydrobenzofurans.

Page/Page column 13, (2008/06/13)
At least one aurone or a natural or synthetic derivative of aurone, or an analogue of aurone, in which the independent phenyl ring can be substituted by a heterocycle of pyrrole, imidazole, triazole, pyridine, furan, or thiophene type, is disclosed as a cosmetic agent, or as an active substance, for the manufacture either of a cosmetic composition, or of a pharmaceutical composition, notably a dermatological composition, having a melanogenesis-inhibiting activity or a depigmenting activity, or an anti-tyrosinase activity.
