The structure of a novel aromatic compound contained in the unidentified Rhizoglyhus mite (Acaridae: Astigmata) was elucidated, without its isolation, to be 3-hydroxybenzene-1,2-dicarbaldehyde (tentatively named γ-acaridial) by a combination of GC/MS and GC/FT-IR together with knowledge of related mite compounds. The structure was confirmed by a 5-step synthesis, starting from methyl 3-hydroxybenzoate, in a 15% overall yield. The compound is widely distributed not only among Astigmata but also among Oribatida, although its biological function is obscure at present.
一种未鉴定的蕈形虫(螨类:无腺螨)中含有的香气化合物的结构被阐明为3-羟基苯-1,2-二甲醛(暂定名为γ-螨醛),未经过分离,结合了气相色谱-质谱(GC/MS)和气相色谱-傅里叶变换红外光谱(GC/FT-IR)的技术,以及相关螨类化合物的知识。该结构通过从甲基3-羟基苯甲酸酯出发的5步合成确认,总体产率为15%。该化合物不仅在无腺螨中广泛分布,也在土壤螨类中存在,尽管其生物功能目前尚不清楚。
