Described herein are hemi-aminal ethers and thioethers of N-alkenyl cyclic compounds that may be produced through a reaction comprising: (A) at least one first reactant represented by a structure (I), wherein X is a functionalized or unfunctionalized C1-C5 alkylene group optionally having one or more heteroatoms, and each R1, R2, and R3 is independently selected from the group consisting of hydrogen and functionalized and unfunctionalized alkyl groups optionally having one or more heteroatoms, and (B) at least one second reactant having at least one hydroxyl moiety or thiol moiety. The hemi-aminal ethers and thioethers of N-alkenyl cyclic compounds may comprise a polymerizable moiety, in which case they may be left as-is or used to create homopolymers or non-homopolymers, or they may not comprise a polymerizable moiety. A wide variety of formulations may be created using the hemi-aminal ethers and thioethers of N-alkenyl cyclic compounds, including personal care, oilfield, and construction formulations.

The present invention provides synthetic routes for preparing various isomers of cyclohexane-based coolants, such as menthyl esters and menthanecarboxamide derivatives, in particular those substituted at the amide nitrogen, for example with an aromatic ring or aryl moiety. Such structures have high cooling potency and long lasting sensory effect, which make them useful in a wide variety of consumer products. One synthetic route involves a copper catalyzed coupling of a primary menthanecarboxamide with an aryl halide, such reaction working best in the presence of potassium phosphate and water. Using this synthetic route, specific isomers can be prepared including the menthanecarboxamide isomer having the same configuration as l-menthol and new isomers such as a neoisomer having opposite stereochemistry at the carboxamide (C-1) position. The neoisomer unexpectedly has potent and long lasting cooling effect. Preparation schemes for neoisomers of other menthyl derivatives which are useful as coolants, including esters, ethers, carboxy esters and other N-substituted carboxamides are also provided.
Provided are compounds described by the Formula I:
wherein: R
1
is a linear or branched, saturated or unsaturated aliphatic group having from 5 to 22 carbon atoms; R
2
is selected from the group consisting of the functional groups:
and salts thererof; n is from 0 to 4; and R
3
is a linear or branched, saturated or unsaturated aliphatic group having from 1 to 6 carbon atoms. Also provided are compositions comprising, and methods of use of, the compounds of the present invention.
