The present invention relates to enaminocarbonyl compounds with the formula I, in which X denotes O or CH
2
, Y denotes N and each of R
1
and R
2
denotes hydrogen, or Y denotes a CH and either R
1
or R
2
denotes a C1-4 alkyl, and the remaining R
1
or R
2
denotes hydrogen, selected (for Y denoting CH and R
1
or R
2
denoting a C
1-4
alkyl) from a group encompassing a mixture of R and S enantiomers enriched in either enantiomer R or enantiomer S, enantiomer R and enantiomer S. The present invention also relates to the use of compounds with the formula I, in which X denotes O or CH
2
, Y denotes a CH and either R
1
or R
2
is selected from a group encompassing hydrogen and a C
1-4
alkyl, and the remaining R
1
or R
2
denotes hydrogen, for the modification of the taste of a product and/or preparation for oral administration.
本发明涉及具有公式I的烯胺酰基化合物,其中X表示O或CH2,Y表示N,且R1和R2中的每一个表示氢,或Y表示CH且R1或R2中的一个表示C1-4烷基,其余的R1或R2表示氢,所选的(对于Y表示CH且R1或R2表示C1-4烷基)从包括富集于R或S对映体的混合物、对映体R或对映体S中选择。本发明还涉及具有公式I的化合物的用途,其中X表示O或CH2,Y表示CH且R1或R2中的一个从包括氢和C1-4烷基的群中选择,其余的R1或R2表示氢,用于改变产品和/或口服制剂的口感。
