摘　　要：Cycloaltilisin 7是从桑科植物面包树(Artocarpus altilis)的芽中分离出的一种新异戊烯基黄烷酮,具有组织蛋白酶K抑制活性;Poinsettifolin B也是从桑科琉桑属植物Dorstenia poinsettifolia中分离出的一种新的香叶基查尔酮,Dorstenia poinsettifolia是原产于喀麦隆潮湿森林的草本植物,用于民间雅司病和伤口感染的治疗,对治疗皮肤病也有潜在功效.以廉价的羟苯乙酮和羟苯甲醛为原料,用简单温和的方法完成了这两种天然产物的首次全合成.所有新化合物的结构都经过HRMS,1H NMR和13C NMR的确认.Cycloaltilisin 7, isolated from the bud covers ofArtocarpus altilis, is a new isoprenyl flavone and has the potential cathepsin K inhibitory activity; while poinsettifolin B is another new geranyl chalcone isolated from the extract of Dorsetenia poinsettifolia, an native cameroonian herb used for the treatment of yaws disease, infection, and other possible skin diseases. Starting from the inexpensive hydroxyl acetophenones and hydroxyl benzaldehydes, the first total syntheses of these two natural products are accomplished with simple and mild conditions. The structures of all new compounds are elucidated by HRMS, ^1H NMR and ^13C NMR spectra.
