Abstract

Abstract Oxidation of 4-alkylpyrocatechols 2 by means of an insect diphenoloxidase (laccase) or K 3 [Fe (CN) 6] yields, in the presence of resorcinols 1 (R 2 [DOUBLE BOND] H), complex mixtures of products from which biphenyltetrols 3 (R 3 [DOUBLE BOND] H) and dibenzofuranones 5 and 6 were isolated. It is suggested that similar homo-coupling products are formed from pyrocatechols 2b and 2c in insects during cuticle sclerotization.
