Abstract

A process for the preparation of 3a, 6, 6, 9a tetramethyl perhydronaphtho £2, 1-b| furan (Ambermor) O comprising: oxidation of sclareol to sclareolide in one single pot process wherein sclareol is dissolved in an inert organic solvent and reacted under strong basic conditions with aqueous solution of hypohalite or periodate, or bromate salts in the presence of catalytic amounts of ruthenium compound from the family of oxides or halides, and optionally in the presence of a phase transfer catalyst, straightforward reduction of the sclareolide in the reaction mixture by any hydride donor known to the art to give selective precipitation of the diol in a pure (100%) form, and cyclization of the diol to the pure (100%) Ambermor.
