PROBLEM TO BE SOLVED: To provide novel bicyclo compounds having flavors useful, e.g., as compound materials of compound perfumes, production methods thereof, and perfume compositions containing the bicyclo compounds.SOLUTION: The present invention provides bicyclo compounds represented by the general formula (1), and perfume compositions containing the bicyclo compounds. (In the formula, R1 to R6 each independently represent a hydrogen atom, or a C1-C10 hydrocarbon group that may be substituted with a hydroxy group, or may form a ring with neighboring R1 to R6 and the bicyclo ring.)COPYRIGHT: (C)2014,JPO&INPIT【課題】調合香料の調合素材などとして有用な香気を持つ新規なビシクロ化合物、その製造方法、および該ビシクロ化合物を含有する香料組成物の提供。【解決手段】一般式(1)で表されるビシクロ化合物、及びこのビシクロ化合物を含有する香料組成物。【化1】(式中、R1~R6は、それぞれ独立して、水素原子、水酸基で置換されていてもよい炭素数1~10の炭化水素基を表すか、隣接するR1~R6とビシクロ環とで環を形成してもよい。)【選択図】 なし
