A highly regio- and stereospecific rhodium-catalyzed allylic alkylation of tertiary allylic alcohol derivatives with a cyanohydrin pronucleophile is described. This direct and operationally simple protocol provides a fundamentally novel approach toward the synthesis of α-quaternary substituted ketones and circumvents many of the inherent problems associated with conventional enolate alkylation reactions

Naturally-derived compounds having various structures elicit the perception of salty taste, enhance the perception of salty taste of a salt, or act at one or more sodium channels. Food products may include such naturally-derived compounds, which may be used to reduce the sodium content, while imparting a similar level of saltiness.
