Provided is an amide ester that is useful as an intermediate manufacturing product for an aroma compound such as spilanthol or the like. Also provided is a spilanthol manufacturing method using said amide ester. High-purity spilanthol can be manufactured by reacting an amide ester represented by general formula (1) with a basic compound.
(In the formula, R1 represents a C1-6 alkyl group or a phenyl group that may be substituted with a C1-4 alkyl group, a C1-4 alkoxy group, or a halogen atom; R2 represents a C1-8 hydrocarbon group; and the wavy lines represent cis configurations, trans configurations, or a mixture of the two configurations.)
提供的是一种酰胺酯,可用作类似spilanthol的香气化合物的中间制造产品。还提供了使用该酰胺酯的spilanthol制造方法。通过将通式(1)表示的酰胺酯与碱性化合物反应,可以制造高纯度的spilanthol。(在公式中,R1表示可以用C1-6烷基或苯基代替的C1-4烷基,C1-4烷氧基或卤素原子; R2表示C1-8碳氢基团; 波浪线表示顺式构型,反式构型或两种构型的混合物。)
