and stereoselective total synthesis of the perylenequinone natural product hypocrellin A (1) is described. The key features include a potentially biomimetic 1,8-diketone aldol cyclization to set the centrochiral C7,C7′-stereochemistry, bis(trifluoroacetoxy)iodobenzene mediated oxygenation, a palladium-catalyzed decarboxylation, and an enantioselective catalytic oxidative 2-naphthol coupling to establish
描述了苝醌天然产物hypocrellin A ( 1 )的有效和立体选择性全合成。主要特征包括潜在的仿生 1,8-二酮醛醇环化以设置中心手性 C7,C7'-立体化学、双(三氟乙酰氧基)碘苯介导的氧化、钯催化脱羧和对映选择性催化氧化 2-萘酚偶联以建立联芳基轴向手性。螺旋立体化学由轴向手性中间体形成,然后用于动态立体化学转移,以决定在羟醛环化过程中形成的 C7、C7'-七元环的立体化学。
