Dehydrogenation with mercuric acetate in the lupane series. Part IV. Acidic products of the reaction
Abstract
The hexacyclic aromatic acid (VId) is formed by dehydrogenation of lupeol derivatives with mercuric acetate. When the reaction is conducted in chloroform–acetic acid solution, there are formed, in addition to the aromatic acid, two hexacyclic homo-acids, which derive the additional carbon atom from chloroform present in the solvent system.
A new homo-acid, formed by extension of the lupeol side-chain is also described.
