Adults of the triatomine bug Triatoma brasiliensis release 2,2,4-triethyl-5-methyl-1,3-dioxolane (1) as a mixture of the (4S,5S)- and (4R,5R)-enantiomers in a ratio of 4:1. Among the volatile acetals identified from insects so far, this is the first example resulting from an intermolecular condensation of a carbonyl moiety and a diol substructure.
三锥猎蝽成虫会释放 2,2,4-三乙基-5-甲基-1,3-二恶烷（1），以（4S,5S）-和（4R,5R）-对映异构体 4:1 的混合物形式释放。在迄今从昆虫中鉴定出的挥发性缩醛中，这是第一个由羰基部分和二醇亚结构的分子间缩合产生的例子。
