    摘要: The present invention concerns some nitrile derivatives of formula (I) wherein R represents a methyl or ethyl group; R
    6 represents a hydrogen atom or a methyl or ethyl group; R
    1 and R
    2 , taken separately, represent each a hydrogen atom or a OR
    7 group, R
    7 being a hydrogen atom or a C
    1-2 alkyl or acyl group; or said R
    1 and R
    2 , taken together, represent an oxygen atom, a CH
    2 group or a carbon-carbon double bond; and - R
    3 , R
    4 and R
    5 are each a hydrogen atom; or - a) R
    5 is a hydrogen atom and R
    3 and R
    4 , taken together, represent an oxygen atom, a CH
    2 group or a carbon-carbon double bond; or - b) R
    4 is a hydrogen atom and R
    3 and R
    5 , taken together, represent an oxygen atom, a CH
    2 group or a carbon-carbon double bond; which are very useful as perfuming ingredients to confer lemon type odor notes.
