Synteesis of 2-Adamantane Carboxylic Acid

Abstract Despite the fact that there are two well-described routes to 2-adamantane carboxylic acid (IV)1,2 it is not an easily accessible compound. In connection with our work in the field of adamantane ketenes and other 2-substituted adamantane derivatives5,6 on adamantanone (I), followed by conversion of the enol ether (II) to the aldehyde (III) and oxidation of the latter to give 2-adanabtabe carvixtkuc acud (IV). The yield of this one-pot procedure is 70%-75% (about 10 runs).

A Convenient Preparation of Malonoylperoxides

Abstract Cyclic Malonoyl peroxides, first reported in 1971 (1) are an important class of compounds for the study of α-lactones (2). These peroxides were prepared by treating a substituted malonic acid with 98% hydrogen peroxide in methanesulfonic acid. A serious disadvantage of this method is the use and the storage of concentrated hydrogen peroxide as well as the remote control device recommended (3) for the operation of this explosive reagent.
