The search for new amber ingredients

There is a constant need for developing new fragrance ingredients in the flavor and fragrance industry, as it allows perfumers to create unique and differentiating perfumes for fine as well as functional products. Among all the categories of notes used in perfume creation, amber notes are indispensible and ubiquitous in their presence in all perfumes. Not only amber notes impart high performance and substantivity to fragrances, but they are paramount in the development of classic and legendary fragrances. This article is based on the plenary lecture delivered at the flavor & fragrance 2013 conference of the German Chemical Society in Leipzig, Germany. The strategy, rationale, and the various synthetic approaches that led to the discovery of two new very powerful, woody, amber materials, Amber Xtreme(®) (1) and Trisamber(®) (2), are delineated.
