    摘要: The present invention relates to a method for synthesising a compound of the following formula (I), where 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), where R and n are as defined above. The invention also relates to a method for assaying the compounds of formula (I) using a corresponding deuterated derivative as an internal reference, as well as to the use of ketal derivatives of compounds of formula (I) as a stable precursor, in particular in a flavouring composition.
