and lonchocarpol-A(senegalensein) were isolated from the rootbark of Citrussinensis var. brasiliensis. Citrunobin and citflavanone were also isolated from the corresponding bark of C. nobilis var. sunki. The structure of citrunobin was elucidated as (E)-1-[7′-hydroxy-5′-methoxy-2′,2′-dimeth-yl-2′H-chromen-8′-yl]-3-(4-hydroxyphenyl)prop-2-enone from spectroscopic and chemical evidence. The absolute
摘要 从 Citrus sinensis var. 的根皮中分离到了一种新的查耳酮,即柑橘苷酸、柠檬黄酮和 lonchocarpol-A(senegalensein)。巴西亚种。Citrunobin 和citflavanone 也从 C. nobilis var. 的相应树皮中分离出来。新奇。citrunobin 的结构被阐明为 (E)-1-[7'-羟基-5'-甲氧基-2',2'-dimeth-yl-2'H-chromen-8'-yl]-3-(4 -羟基苯基)丙-2-烯酮来自光谱和化学证据。citflavanone 和 lonchocarpol-A 的绝对构型从它们的 CD 光谱数据确定为 2S。

New and efficient synthetic approaches to the biologicallyinteresting natural products citrunobin, boesenbergins A and B, xanthohumol C, and glabrachromene are described. The key strategies involve ethylenediamine diacetate catalyzed benzopyran formation reactions and base-catalyzed aldol reactions.
