(5 R*,9S*)- and (5R*,9R*)-2,2,9-Trimethyl-1,6-dioxaspiro [4.4]non-3-ene (1a and 1b resp.) and their dihydro derivatives 2a and 2b are described as new constituents of geranium oil. The structures and configurations of 1a, 1b, 2a, and 2b, are based on spectra interpretation and syntheses. Also some other monoterpenoid constituents identified in the same boiling range are discussed.
(5 R *,9 S *)-和(5 R *,9 R *)-2,2,9-三甲基-1,6-二氧杂螺[4.4] non-3-ene(分别为1a和1b)和它们的二氢衍生物2a和2b被描述为天竺葵油的新成分。1a,1b,2a和2b的结构和配置基于光谱解释和合成。还讨论了在相同沸腾范围内鉴定出的其他一些单萜类成分。
