A lactone compound is represented by general formula (A), and an ether compound is represented by general formula (B). In formula (A), R is a hydrogen atom or R1. When R is a hydrogen atom, R′ is R1, the carbon bond (1) is a single bond or a double bond, and the carbon bond (2) is a single bond. When R is R1, R′ is a hydrogen atom or R1, both the carbon bonds (1) and (2) are a single bond, or one of them is a double bond and the other is a single bond. In formula (B), R″ is R1. R1 represents a specific alkyl group, a specific alkenyl group, a specific alkynyl group, or an aryl group. In formulas (A) and (B), n is 0 or 1.
一种内酯化合物由通式(A)表示,一种醚化合物由通式(B)表示。在通式(A)中,R是氢原子或R1。当R是氢原子时,R′是R1,碳键(1)是单键或双键,碳键(2)是单键。当R是R1时,R′是氢原子或R1,碳键(1)和(2)都是单键,或其中一个是双键,另一个是单键。在通式(B)中,R″是R1。R1代表一个特定的烷基基团,一个特定的烯基基团,一个特定的炔基基团或芳基。在通式(A)和(B)中,n为0或1。
