Ketocampholenic acid derivatives, their use, and methods of preparing these derivatives are described. In one aspect, novel derivatives of 2-oxo-4,5,5-trimethylcyclopent-3-enylacetic acid (herein further referred as ketocampholenic acid or KCA), which is a natural product that may be prepared by microbial biological oxidation of camphor or of a suitable precursor, are described. Novel derivative compounds may be prepared according to the methods described in the present invention. Such derivative olfactory properties that make them useful in fragrance and flavor applications.
描述了Ketocampholenic酸衍生物、它们的用途以及制备这些衍生物的方法。在一个方面,描述了2-氧代-4,5,5-三甲基环戊-3-烯基乙酸(以下简称为Ketocampholenic酸或KCA)的新衍生物,这是一种天然产物,可以通过对藿香脑或适当前体进行微生物生物氧化来制备。根据本发明描述的方法可以制备新的衍生物化合物。这些衍生物具有使它们在香味和风味应用中有用的嗅觉特性。
