C4‐C5 periannulation of 1‐naphthols and ynones via BF3.Et2O mediated one‐pot cascade under metal and solvent‐free conditions have been developed for the synthesis of perinaphthenones. Furthermore, this strategy features the formation of new periannulation at C4‐C5 positions of α‐naphthol, synthesis of highly substituted perinaphthenones, broad substrate scope, readily available starting materials and
通过BF 3对1-萘酚和炔酮进行C 4- C 5环环化。已经开发了在无金属和无溶剂条件下由Et 2 O介导的一锅级联反应,用于合成环萘醌。此外,该策略的特征是在α-萘酚的C 4 -C 5位置形成新的环戊二烯,合成高度取代的环萘醌,广泛的底物范围,易于获得的起始原料以及良好的中度收率。在这里合成的perinaphthenones产品表现出有趣的光物理性质
