The present invention relates to novel pyrimidine derivatives and their use in perfume compositions. The novel pyrimidine derivatives of the present invention are represented by the following formula:
wherein m and n are integers that when m is 0, n is 1; when m is 1, n is 0 or 1; or when m is 2, n is 0;
wherein (CH)
m
and (CH)
n
are each independently optionally substituted with a substituent selected from the group consisting of methyl and ethyl;
wherein X is selected from the group consisting of N, O, and S; and
wherein R
1
and R
2
each independently represent H or a hydrocarbon group, or R
1
and R
2
together represent a fused ring or a ring system,
with the proviso that when R
1
is H, R
2
is not H.

嘧啶衍
生物由以下公式表示:其中m和n是整数,当m为0时,n为1;当m为1时,n为0或1;或当m为2时,n为0;其中(CH)m和(CH)n各自独立地可选地被取代为
甲基和乙基中的一种取代基;其中X从N、O和S中选择;其中R1和R2各自独立地表示H或一个
碳氢基团,或者R1和R2一起表示一个融合环或一个环系统,但当R1为H时,R2不为H。
