Shaping Scents: Metathesis in Pheromone Synthesis

At Apeiron, we specialize in advanced metathesis chemistry, providing innovative solutions for the synthesis of complex molecules. One exciting area where this expertise truly matters is in the synthesis of pheromones—nature’s highly specific communication signals. These compounds are widely used in agriculture for environmentally friendly pest control and inspire new fragrance ingredients, including musk-like notes prized in perfumery.

Why Pheromones?

Pheromones are structurally diverse, often unsaturated molecules with precisely placed double bonds. Their biological activity depends on this exact molecular geometry, which makes synthesis challenging. Traditional methods are often lengthy and inefficient.

That’s why metathesis, and especially cross metathesis, has become a game-changer. By using carefully designed Ru catalysts, chemists can construct the double-bond frameworks of pheromones in a direct and predictable way.

How does Cross Metathesis work?

Cross metathesis allows two alkenes to exchange partners, forming new carbon–carbon double bonds. This simple idea has enormous power in pheromone synthesis, where it provides:

• Efficiency: Shorter synthetic routes compared to classical methods.
• Precision: Reliable control of alkene geometry (E/Z-selectivity).
• Flexibility: Access to diverse pheromone structures from common building blocks.

Modern Ru catalysts are especially well-suited because of their functional group tolerance—they perform in the presence of esters, alcohols, acids, and other sensitive groups common in pheromone chemistry.

Apeiron’s Contribution: CAACs and Low Loadings

At Apeiron, we don’t just use metathesis catalysts—we innovate them. Our work on CAAC (Cyclic Alkyl Amino Carbene) ligands has led to next-generation Ru catalysts with enhanced stability, selectivity, and reactivity. Importantly, these catalysts can operate at extremely low loadings, making large-scale pheromone synthesis more cost-effective and sustainable.

This combination of cross metathesis, Ru catalyst tolerance, and CAAC technology gives Apeiron’s partners unique advantages in developing pheromones for agriculture and fragrances.

Shaping the Future of Scents

By advancing metathesis and cross metathesis, Apeiron is helping industry partners produce pheromones more efficiently and sustainably. Whether applied to green pest management or to the design of new musk-inspired fragrances, our expertise ensures reliable access to the molecules that shape the scents of tomorrow.
