Attorney, Agent or Firm:
In one of its embodiments the present invention provides a smoking composition which contains a novel type of acylpyrazine ether flavorant additive as exemplified by 1-(3-methoxy-2-pyrazinyl)-2-methyl-1-propanone. ##STR1## |
|
DETAILED DESCRIPTION What is claimed is: 1. An acylpyrazine ether corresponding to the formula: ##STR19## where R is a substituent selected from aliphatic, alicyclic and aromatic hydrocarbyl groups having 2-12 carbon atoms, R. sup. 1 is a substituent selected from hydrogen and alkyl groups having 1-6 carbon atoms, X is etheric oxygen or sulfur, and R. sup. 2 is a substituent selected from aliphatic, alicyclic and aromatic hydrocarbyl groups having 1-12 carbon atoms, with the proviso that the position-(3) substituent is not hydrogen. 2. 1-(3-Ethylthio-2-pyrazinyl)-1-propanone. 3. 1-(3-Methoxy-2-pyrazinyl)-2-methyl-1-propanone. 4. 1-(3-Furfurylthio-2-pyrazinyl)-2-methyl-1-propanone. 5. 1-[3,6-Dimethyl-5-(cis-hex-3-enoxy)-2-pyrazinyl]-1-propanone. 6. A halo-acylpyrazine corresponding to the formula: ##STR20## where Y is a halogen atom, R is a substituent selected from aliphatic, alicyclic and aromatic hydrocarbyl groups having 2-12 carbon atoms, and R. sup. 1 is a substituent selected from hydrogen and alkyl groups having 1-6 carbon atoms, with the proviso that the position-(2) substituent is not hydrogen. 7. 1-(3-Chloro-2-pyrazinyl)-1-propanone. 8. 1-(3-Chloro-2-pyrazinyl)-2-methyl-1-propanone. 9. 1-(5-Chloro-3,6-dimethyl-2-pyrazinyl)-1-propanone. 10. A halo-acylpyrazine corresponding to the formula: ##STR21## where Y is a chlorine atom, R is a substituent selected from aliphatic, alicylclic and aromatic hydrocarbyl groups having 2-12 carbon atoms, and R. sup. 1 is a substituent selected from hydrogen and alkyl groups having 1-6 carbon atoms, with the proviso that the position-(2) substituent is not hydrogen. 11. A halo-acylpyrazine corresponding to the formula: ##STR22## where Y is a bromine atom, R is a substituent selected from aliphatic, alicylclic and aromatic hydrocarbyl groups having 2-12 carbon atoms, and R. sup. 1 is a substituent selected from hydrogen and alkyl groups having 1-6 carbon atoms, with the proviso that the position-(2) substituent is not hydrogen.
Description:
BACKGROUND OF THE INVENTION Alkylpyrazines are typical of organic compounds which have been recognized as having useful properties for application as flavorants in tobacco and foodstuffs
