“…The DSM company has recently patented the use of a gold complex (I) for the synthesis of a cyclademol intermediate (28). [24] This alcohol finds its origin in terpene chemistry, in particular via myrcene (29), [25] and allowed the synthesis of various compounds of great interest in perfumery for the elaboration of musky compositions (Scheme 10). [26] It is interesting to note here the apolar sequence -ether/ester À (CH 2 ) 1 or 2 -ester which could "characterize" the musky odor of these substrates.…”

Over the last century, the fragrance industry had relied on the synthetic chemists for the development of new odors, but also for the replacement of some known materials due to allergy or toxicity. Transition metal‐catalyzed transformations have allowed atom economy and synthetic efficiency for several transformations and they caught the attention of fragrance industrials. The metal‐catalyzed cyclization reactions have been particularly successful toward the synthesis of key skeletons. This review highlights the developments of selected hedonic materials according to transition metal‐catalyzed according to cycloisomerization reactions and related rearrangements.

“…Hansen via a heterologous expressed farnesyl synthase from sweet wormwood, Artemisia annua L. Since S. cerevisiae tolerates high concentrations of up to 23.8 g of β‐farnesene ( 230 ) per 100 g of glucose, the process is highly productive as the β‐farnesene ( 230 ) easily separates from the culture broth. It is sold as sustainable and inexpensive biofuel under the name “Biofene” [209,210] . As delineated in Scheme 29, Biofene ( 230 ) is however more than a biofuel as it is also the starting material for a 3‐step biotechnological process to (−)‐Ambrox ( 229 ) or Ambrofix ( 229 ) as it is called in Givaudan [211] .…”

In this review, the impact of the transition from today’s petrochemical economy towards a 100/100 renewable and biodegradable future is discussed: “citrus”, “green”, “fruity”, “floral”, “floriental”, “oriental”, “woody”, “chypre” and “fougère”. After benchmark data on ingredients usage, definitions on biodegradation and sustainability are given. Celebrating the 150th anniversary of svanillin, its historic synthesis from renewable starting materials serves as introduction. Citrus scents upcycled from the beverages industry are already an ideal case for 100/100 with new opportunities for artificial essential oils. In the fruity domain, transparent and lactonic ingredients are available in a sustainable manner. In the domain of green odorants, there is a lack of green chemistry for important key materials. In the floral family, renewability is more critical than biodegradability, but cost is an issue. Thanks to Ambrox and maltol, florientals and orientals will persist, while woody notes severely lack an Iso E Super replacer. In the chypre genre, patchouli became the new moss, but more musks are increasingly in demand. With their high percentage of linalool and dihydromyrcenol, the construction of fougères could well become a precedent for other families, despite challenges in vetiver and salicylates. Still, the challenges exemplified create immense opportunities for new perfumery materials
