The present invention relates to a method for synthetizing a compound of the following formula (I):
wherein R is a methyl or ethyl group, n is 1 or 2, and X is a CH
2
or CD
2
group, from a compound of the following formula (II):
wherein R and n are as defined above,
and also relates to a method for assaying the compounds of the formula (I) using a corresponding deuterated derivative as an internal reference, as well as to the use of ketal derivatives of compounds of the formula (I) as a stable precursor, in particular in a flavoring composition.
本发明涉及一种从以下式(I)的化合物合成方法:其中R为甲基或乙基基团,n为1或2,X为CH2或CD2基团,从以下式(II)的化合物开始:其中R和n如上所定义,并且涉及一种使用相应的氘代衍生物作为内部参考的方法来测定式(I)的化合物,以及将式(I)的化合物的缩酮衍生物用作稳定前体的用途,特别是在调味组合物中。
