Moschusduft und Patchouliöl

Synthetic musk odours and patchouli oil are widely used in the production of cosmetics and scented household goods. In many perfumes one or both substances are key fragrances to create a unique and luxury odour. While patchouli oil is an essential oil from the patchouli plant, natural musk is historically an animal secrete which is derived from a gland of the muskdeer. The progress in organic synthesis has led to numerous synthetic musk‐like fragrance compounds. Both methods, the plant based production as well as the industrial synthesis of fragrances are connected to challenges such as ethic concerns and possible environmental risks. Therefore, sustainable chemical processes as well as biotechnological methods for the future production of important perfumery ingredients are developed.     

The Prins Reaction in the Fragrance Industry: 100th Anniversary (1919–2019)

The Prins reaction, an acid‐catalyzed condensation of alkenes with aldehydes, is used extensively in the fragrance industry. This year we celebrate the 100th anniversary of the discovery of this reaction. In honor of this occasion we present an overview of the diverse applications of the Prins reaction in the synthesis of flavor and fragrance ingredients. To pay tribute to the inventor of the Prins reaction, Hendrik Jacobus Prins, we also provide some insight into his life, scientific, and entrepreneurial accomplishments.
