monoterpene lactone from the acarid mite, Schwiebea araujoae, was elucidated without its isolation by GC/FT-IR and GC/MS analyses to be 3-(4-methyl-3-pentenyl)-2(5H)-furanone (1) and tentatively named as alpha,alpha-acariolide. The structure of 1 was identified by its synthesis from alpha-bromo-gamma-butyrolactone via 4 reaction steps. The synthesized compound gave the same GC/MS and GC/FT-IR spectra as those
未经螨类鉴定的螨类新单萜内酯未经GC / FT-IR和GC / MS分析即分离为3-(4-甲基-3-戊烯基)-2(5H)-呋喃酮(1 ),并暂时命名为alpha,alpha-acariolide。1的结构通过4个反应步骤由α-溴-γ-丁内酯合成而确定。合成的化合物具有与天然产物相同的GC / MS和GC / FT-IR光谱。同样从未知的螨虫中阐明了另一种单萜内酯为4-(4-甲基-3-戊烯基)-2(5H)-呋喃酮(2),并命名为α,β-阿糖胞苷。还可以通过5个反应步骤从相同的丁内酯作为起始原料进行合成来鉴定。制剂的GC / MS和GC / FT-IR光谱与天然产物的光谱相同。
