The present invention relates to a certain heterocyclic pyrimidine and its use in processes and compositions for altering the flavors and aromas of various materials such as tobaccos, foodstuffs, and the like, as well as the novel pyrimidines and processes for producing them.
Because of the tremendous consumption of foods, tobaccos, and other materials, there has been an increasing interest in substances and methods for imparting flavors to such consumable materials. This interest has been stimulated not only because of the inadequate quantity of natural flavoring materials available, but perhaps even more importantly, because of the need for materials which can combine several nuances, will be more stable than natural materials, will blend better with other flavors or flavoring composition components, and will generally provide superior products.
Various pyrimidines containing 4-substituents have been shown in the art, but no flavoring, enhancing or other organoleptic properties have been shown or suggested. Thus, U.S. Pat. No. 3,272,811 shows a variety of pyrimidine.
