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 R1 and R2 each independently represent H or a hydrocarbon group, or R1 and R2 together represent a fused ring or a ring system,
with the proviso that when R1 is H, R2 is not H.
本发明涉及新型嘧啶衍生物及其在香料组合物中的使用。本发明的新型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从甲基和乙基组成的群体中选择的取代基;其中X从N、O和S中选择;且其中R1和R2各自独立地代表氢或一个碳氢基团,或者R1和R2一起代表一个融合环或一个环系统,但当R1为氢时,R2不为氢。
