Popis:	An unexpected formation of cis-1,2,2-trimethyl-3-(benzoxazol-2-yl)cyclopenta-necarboxylic acids was observed as the result of an oxidative C-C bond cleavage of the camphor ring in the intermediate imine during the condensation reactions between camphoroquinone and o-aminophenols conducted under open air conditions.
