  • Patent number: 7935848
    Abstract: Cooling compounds of formula (I) wherein R1 is selected from the group consisting of hydrogen, methyl, C1-C3 alkoxy, phenyl, C1-C3 alkylphenyl, C1-C3 alkoxyphenyl, thienyl, pyridyl, furyl, and indoyl; R2 is selected from the group consisting of hydrogen and hydroxyl, or R2 forms together with the carbon atom to which it is attached a carbonyl group; and R3 is selected from the group consisting of 2,4-dimethylpent-3-yl, 2,3,4-trimethylpent-3-yl, adamantyl and 2-isopropyl-5-methyl-cyclohexyl-1-yl; and, product compositions comprising them.
    Type: Grant

  • Patent number: 7880011
    Abstract: A method of making a compound of formula II comprising the reaction of a compound of formula RCONH2 with a compound of formula III R being a moiety having between 1 and 15 carbon atoms and optionally from 1 to 5 heteroatoms independently selected from oxygen, nitrogen and sulfur, and X and Y being independently selected front the group consisting of H, methyl, ethyl, OMe, OEt, and mixtures thereof; the reaction being performed in a solvent in the presence of a base. The method is useful for the inexpensive manufacture of certain commercially-valuable compounds, including some that have desirable cooling properties.
