Clove oil is an essential oil that can be derived into various aroma chemicals for flavor and fragrance ingredients.1 The main components in clove oil are eugenol and caryophyllene, which could be synthesized into more than 15 derivatives such as isoeugenol, methyl isoeugenol, and vanillin.1 The latest synthesis technology uses sustainable innovation and green chemistry, such as a catalytic process for isoeugenol and dihydroeugenol, which have 100% atom economy, meaning all reagents are converted into the desired product without producing waste that pollutes the environment. The same thing happens in developing catalytic oxidation technology for the synthesis of vanillin made from eugenol, using green chemistry resulting in environmentally friendly and economical processes.
