and their structures elucidated by NMR spectroscopy. Some hydroxylated menthols showed plant growth inhibitory and strong mosquito repellent activity. Among the hydroxylated cineoles, microbial and animal metabolites of cineoles were included. From ent-kauranes, a plant growth inhibitory diterpene alcohol, (−)-16α-hydroxy kaurane was obtained along with 16α-kauran-13α-ol.
摘要 间氯过苯甲酸或干臭氧氧化了六种单萜类化合物 l-薄荷醇、l-乙酸薄荷酯、异薄荷醇、新薄荷醇、1,4-桉树脑和 1,8-桉树脑和一种双萜烃 ent-kaurene。得到各种羟基化产物及其核磁共振谱阐明的结构。一些羟基化薄荷醇显示出植物生长抑制和强烈的驱蚊活性。在羟基化桉树脑中,包括桉树脑的微生物和动物代谢物。从 ent-kaurane 中获得了植物生长抑制性二萜醇 (-)-16α-羟基 kaurane 以及 16α-kauran-13α-ol。
