-The oxidation of 2,2-di(3,5-di-t-butyl-4-hydroxyphenyl)indan-1,3-dione by potassium hexacyanoferrate(III) afforded a trispiro-conjoined cyclopropane compound due to the bond formation between the ipso-carbons. Its cyclopropane ring was found to exist in solution in dynamic equilibrium with biradical species by the dissociation of the C-C bond, which is as long as 1.595 ? as revealed by X-ray crystal analysis.
On the reaction of the 5-lipoxygenase-inhibitor 2-(3,5-di-tert-butyl-4- hydroxyphenyl)-3-hydroxy-1,4-naphthoquinone with Mel/Ag2O

The reaction of the title compound 1, a selective 5-lipoxygenase inhibitor, with Mel/Ag2O results in a mixture of 3 by ring contraction and 6/7 by epoxidation. 3 is the main product up to now isolated only in traces by the reaction of 1/2 with
