The formation of methylenebis(chalcone)s has been discovered during deprotection with methoxymethyl groups from trihydroxychalcones. Studies on this methylenation reaction led to a mechanism hypothesis that was extended to other chalcones and to dihydrochalcone, acetophenone, benzophenone and flavone derivatives. This new method was applied to the rapid synthesis of natural product piperanduncin C. These original methylenebis compounds were also evaluated for their antiparasitic activity. Copyright

The invention primarily relates to aroma compositions of (i) certain saliva-stimulating alkamides having a tingling, pungent and/or hot flavor (such as for example pellitorines, spilanthol) with (ii) hesperetin (5,7-dihydroxy-3-(3-hydroxy-4-methoxyphenyl)-chroman-4-one) or the enantiomers and/or salts thereof and/or (iii) 4-hydroxydihydrochalcones (3-(4-hydroxyphenyl)-1-phenylpropan-1-ones) and/or the salts thereof, the use thereof to enhance the sweet flavor of sweet-tasting substances or the sweet odor impression of aroma substances which give rise to a sweet odor impression, but in particular to enhance the sweet initial flavor or odor (initial sweetness). The invention thus relates to the use of said aroma compositions as general sweetness enhancers and enhancers of initial sweetness. The invention further relates to certain preparations which contain an effective amount of said aroma compositions of (i) alkamides (such as in particular pellitorines, spilanthol) with (ii) hesperetin or the enantiomers and/or salts thereof and/or (iii) 4-hydroxydihydrochalcones and/or the salts thereof and methods for enhancing the sweet flavor or initial sweetness of a sweet-tasting substance or the sweet odor impression or initial sweetness of an aroma substance which gives rise to a sweet odor impression. The invention also relates to the use of certain alkamides (i) to enhance the initial sweetness of a preparation comprising (ii) hesperetin or the enantiomers and/or salts thereof and/or (iii) 4-hydroxydihydrochalcones and/or the salts thereof and (b) sweet-tasting substances and/or (c) aroma substances which give rise to a sweet odor impression.
