    摘要: The present invention describes a novel synthetic method for preparing the key intermediate 2,6,10-trimethyl-1,1-dialkoxy-3,5,9-undecatriene of lycopene. An existing synthetic method have some disadvantages that it is very difficult to gain the raw material dialkyl 4-methyl-5,5-diakoxy-1-pentene-1-phosphonate (10) because no effective synthetic method can be adopted, and furthermore the obtained target compound is composed of several cis/trans isomers. This invention relates to a process comprising a condensation step wherein a starting C10-phosphonate is changed to its carbanion completely at a temperature of −40˜30 under an atmosphere of a non-reactive gas in an organic solvent catalyzed by base, and then C4-dialkyl is added to undergo Wittig-Horner condensation. This invention affords all trans C14-acetal and this method is characterized with the advantages of simple procedure, easy access to raw material and low cost, which makes it has the value of industrial application.

    摘要: The present application provides a synthetic spilanthol flavor composition that includes (2E,6Z,8E)-N-(2-methylpropyl)-2,6,8-decatrienamide. The synthetic spilanthol composition can also contain, and at least one of (2E,6E,8E)-N-(2-methylpropyl)-2,6,8-decatrienamide and (2E,6Z,8Z)—N-(2-methylpropyl)-2,6,8-decatrienamide, the (N-(2-methylpropyl)-2,6,8-decatrienamide being present in amounts effective to impart a salivating or tingle effect while reducing the perception of off notes, as compared to the off-notes perceived upon consumption of natural spilanthol (e.g. spilanthol obtained from jambu oleoresin). Methods of increasing salivation and/or providing a tingling sensation upon consuming an orally consumable product that include adding to the product a synthetic spilanthol flavor composition are also provided. Synthetic spilanthol flavor compositions can be added to orally consumed products, such as, but not limited to, foods, beverages, pharmaceuticals, nutraceuticals, or therapeutic compositions, oral personal care products, gums (e.g. chewing gum or bubble gum), candy or lozenges.
