(-)-sclareol. The divergent translational potential of (+)-yahazunol was demonstrated by the expedient preparation of (-)-zonarone, (-)-isozonarone, (-)-zonarol, (-)-isozonarol, (+)-chromazonarol, and (+)-yahazunone. This approach also enables the formal synthesis of puupehenol, puupehedione, and hongoquercin A. Antifungal evaluation was performed, and this represents the first biological profiles for (+)-yahazunone
描述了(+)-亚哈祖诺及其相关天然产物的有效合成和抗真菌研究。该策略的核心是Barton脱羧偶联,包括一锅自由基脱羧和醌加成级联反应。(+)-yahazunol的可扩展合成是从市售和廉价的(-)-香紫苏醇开始的五个最长线性序列(LLS)中完成的。(+)-yahazunol的不同翻译潜能由(-)-zonarone,(-)-isozonarone,(-)-zonarol,(-)-isozonarol,(+)-chromazonarol和(+ )-yahazunone。这种方法还可以使puupehenol,puupehedione和hongoquercin A正式合成。进行了抗真菌评估,这是(+)-yahazunone,(+)-8-O-乙酰基Yahazunone,和(+)-8-O-乙酰基亚氮唑醇。(+)-氯马那洛尔和(+)-Yahazunone是抗核盘菌的有前途的候选物,EC50值分别为24.1和28
