月光花素甲(Calonyctin A)是从月光花[Calonyction aculeatum(L.)House]叶中分离获得的一种高活性的植物生长抑制剂,经IR、NMR及MS分析证明,它是药喇叭酸乙酯的五聚糖甙,其甙元为dl-11-羟基十六烷酸乙酯。 Tomecko和Adams及Davies和Adams曾合成11-羟基十六烷酸甲酯。我们采用如下改进方法合成dl-11-羟基十六烷酸乙酯。
Calonyctin A is a highly active plant growth inhibitor isolated from the leaves of Calonyction aculeatum (L.) House. It has been proved by IR, NMR and MS that it is an agonist Ethyl pentasaccharide glycosides, the aglucone yuan for the dl-11-hydroxy hexadecanoate ethyl. Tomecko and Adams and Davies and Adams have synthesized methyl 11-hydroxyhexadecanoate. We use the following improvements to synthesize dl-11-hydroxyhexadecanoic acid ethyl ester.
