The purpose of this paper is to give an overview of our intense synthetic efforts that have been expended in the quest for novel fragrance ingredients. Carbon-carbon bond formation is at the heart of organic synthesis. 1 Several examples will be presented, which will highlight the utility of diverse synthetic reactions such as Diels-Alder, Mannich, ene reactions, etc. that have been used to uncover highly desirable aroma chemicals (Iso E Super, Lyral, Triplal [or Aldehyde AA], Isocyclocitral and so forth; F-1).

Qualitative odor-structure relationships have been applied for more than a century. The results of these studies are mostly the consequence (outcome) of the application of common sense gathered by experience. Two main features characterize the molecular structures of odorant molecules: “electronicity” (electronic charge distribution over a molecule) and “stereocity” (volume, shape and profile of a molecule).

A look at the four groups that comprise this section of heterocyclic chemicals, and their importance to fl avors and fragrances. Of the ca. 20 million chemical compounds presently characterized, almost half are heterocyclic molecules. Heterocyclic molecules are significant due to their abundance in nature, and their chemical and biological importance.
