Catalysis in the preparation of fragrances and flavours Original Research Article

This review, with more than 250 references in the field of fragrance and flavour chemistry, summarises recent progress in industrial catalysis. Applications in classical reactions, such as hydrogenations, isomerisations, hydride reductions, oxidations, hydroformylations, metathesis, aldol and Friedel–Crafts condensations in achiral, racemic and asymmetric fashion are discussed.
