antitumor activities. (+)-Albaconol, (+)-neoalbaconol, and two (+)-yahazunol isomers (24 and 25) proved to be the novel pharmaceutical leads. The probable macromolecular targets were estimated to deliver new information about the biological potentials resident in (+)-yahazunol relevant products. This work also featured the first synthesis of (+)-albaconol and (+)-neoalbaconol, the first biological exploration

Environmentally benign and highly atom economic catalytic Friedel-Crafts alkylation reaction and diastereoselective C-O bond formation reaction has been developed. The scope and generality of this reaction was amply illustrated by synthesis of chromazonarol, hongoquercin A and B and analogues thereof.
已开发出环境友好且具有高原子经济性的催化 Friedel-Crafts 烷基化反应和非对映选择性 CO 键形成反应。该反应的范围和一般性通过 chromazonarol、hongoquercin A 和 B 及其类似物的合成得到充分说明。

The specifics: A synthesis of the sesquiterpenoid antibiotic (+)‐hongoquercin A using sequential site‐specific CH methylation and oxidation reactions is described. A key advancement toward this goal was the development of a ligand‐accelerated CH methylation reaction, and enabled the generation of a library of eight structurally diverse analogues.
细节:所述倍半萜类抗生素(+)的合成-使用位点特异性顺序hongoquercin A C ħ甲基化反应和氧化反应进行说明。实现该目标的关键进展是开发了配体促进的CH甲基化反应,并能够生成八种结构多样的类似物。

(-)-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
